Week 12



Welcome back from Easter Break. This week we will be talking about static and current electricity, applying what we learn to a series of explorations and activities. On Thursday we will construct series and parallel circuits, talk more about Ohm's law and cells. Be sure to read your chapter before Thursday. If time, we will begin our discussion of magnetism.

Question 9 How are magnetism and electricity similar and different? Be specific and give examples. – blog about this.
Have a great week,
Dr. E

    How are magnetism and electricity similar and different? Be specific and give examples.
    Just as magnets can attract or repel each other, electrically charged objects can do the same. In the balloon project we did in class we experimented with electrically charging the balloons to make them either repel or attract each other. Like magnets, opposite charges attract and like charges repel. However, electric charges are different than magnets because the magnets cannot change their force. Electric charges can change from a positive to negative or negative to positive charge.

    How are magnetism and electricity similar and different? Be specific and give examples.

    In both electricity and magnetism, opposites attract. In the experiment we did in class yesterday, we did a few different things to see what would make the balloons attract to one another and what would make them repel. When we rubbed the balloons on our head, the balloons repelled from one another.

    The north and south poles of a magnet will remain unchanged, unlike the electric charge of an object, which can change from negative to positive or from positive to negative.

    Opposites attract in both magnetism and electricity. The experiments we did in class on Tuesday and Thursday were great examples of the two. With Magnetism the north and south poles cannot be changed and the side that has more electrons on it will remain that way. With Electricity the sides can change from being positive to negative or negative to positive.

    How are magnetism and electricity similar and different?

    Magnets and electricity both creates attractions. Magnets have botha negative and a positive attraction and electricity has different currents. What's different about electricity is that the poles of and electric charge never change and magnetic charge can.

    Magnetism and electricity both attract and repel without touching. Magnets can't change their poles but electricity can.

    Magnetism and electricy are similar because they can both attract or repel something without touching it. They are different because the charge of the poles cannot change in a magnet, but can with electricity.

    Magnetic force and electrical forces are similar because they can both attract and repel without touching (depending on which end of the magnet is held near another). They differ because the forces between electic charges repel one another and unlike charges attract.

    Magnetism and electricity are similar in that they both attract and repel things with out touching. This is shown with magnets and metal objects and charged baloon against an uncharged baloon. They are different in that electricity can change poles of negative and positive charges. And electricity is used with many objects not only objects that are magnetic.

    How are magnetism and electricity similar and different?

    Magnetism and electricity are similar because they can attract and repel different things. An example of the attraction and repelling of an object is the activity that we did in class with the balloons. We were able to attract or repel the two balloons. Magnetism and electricity are different because magnets can not change the positive and negative forces.

    Both magnets and electricity attract one another. Magnets have a negative and positive attraction, where electricity has different currents.

    Both can repel and attract the objects. In we experimented withb balloons and electrically charging the balloons to make them repel and attract each other. Like magnets, opposite charges attract and like charges repel. They are differnt because electricity can change charges while magnets can not. Electric charges can change from a positive to negative or negative to positive charge.

    Magnets and electricity are both capable of attraction and repulsion. Magnets have positive and negative charges, while electricity uses currents. In class, we looked at a couple of different examples of magnetism and electricity. By using balloons we could see the repulsion of a charged balloon when next to an uncharged balloon. Also, by building different types of circuits we were able to observe electrical currents.

    Magnets and electricity have many things in common. They both attract and repel depending on poles for magnets and charges for electricity. With magnets the north pole attracts the south pole and repels another north pole.

    Magnets and electricity have many similarities and differences. They both are capable of repulsion and attraction. Magnets have a north and south pole, and only attract to the opposite. (north to south and south to north)Unlike magnets, electricity is not able to change their poles.

    How are magnetism and electricity similar and different?

    Magnets have a north and south pole (a standard bar magnet) while electric currents have a positive and negative charge (a battery). They similar because that both can repel and attract. In an electric current, a positive charge attracts a negative charge, negative charge attracts a positive charge, positive charge repels a positive charge, negative charge repels a negative charge. With magnetism, north attracts south, south attracts north, north repels north and south repels south.

    How are magnetism and electricity similar and different?

    Magnets and electricity both are capable to attract and repel. With electricity, a positive charge attracts a negative charge, and vice versa, and does the same with repelling charges. With magnetism, the north and south poles do the same as positive and negative charges in electricity. North poles attract south poles, and vice versa.
