Motor magnet

The video tutorial explains the interaction between currents and magnets, demonstrating how a current can exert a force on a magnet. It illustrates this concept by showing how a magnet can stick to a battery and how running a current through a wire can make the magnet spin, highlighting the practical application of these principles.

What can a current do in relation to a magnet?

• It can make a magnet disappear.

• It can apply a force to a magnet.

• It can only repel a magnet.

• It can change the color of a magnet.

What happens when a screw or nail is placed near a magnet?

• It will float in the air.

• It will change color.

• It will stick to the magnet.

• It will melt.

Where does the metallic object stick when attached to a magnet?

• To the bottom of the battery.

• To the side of the battery.

• To the middle of the battery.

• To the top of the battery.

What effect does running a current through a wire have on a magnet?

• It makes the magnet disappear.

• It changes the magnet's color.

• It makes the magnet heavier.

• It causes the magnet to spin.

What is demonstrated when a current causes a magnet to spin?

• The magnet's size doubles.

• The magnet's weight increases.

• The magnet's temperature decreases.

• The practical application of electromagnetic forces.
