Magnetism

Front

If you break a bar magnet in half, each half:

Back

becomes a bar magnet with 2 poles

Front

Magnetic field strength is:

Back

strongest closest to the poles

Front

The magnitude of the force acting on a moving charge through a magnetic field is not dependent on

Back

The direction of the magnetic field

Front

In the picture, what direction is the current flowing in?

Back

In the direction of the thumb

Front

Where is field strength the strongest in a current carrying wire?

Back

closest to the wire

Front

What does Earth’s magnetic field do?

Back

Protects us from the Sun’s radiation and causes the Aurora Borealis.

Front

Magnetic poles are similar to electric charges in that they both can repel and attract one another.

Back

True

Front

Is it easy to isolate one pole of a magnet, just as it is easy to separate electric charges?

Back

False

Front

The magnetic field lines around a wire carrying a current form a series of concentric circles around the wire.

Back

True

Front

We can begin with electricity and get magnetism. If we start with magnetism cannot get electricity.

Back

False
