Magnetism

Magnetic field lines originate from the:

• South pole and terminate at the North pole

• North pole and terminate at the South pole

• Positive charge to negative charge

• None of the above

The SI unit of magnetic field strength is

• Newton

• Weber

• Tesla

• Coulomb

What happens when two similar magnetic poles are brought close together?

• They attract each other.

• They repel each other.

• They cancel out each other's field.

• They do not interact.

The strength of a magnetic field is highest at:

• The center of the magnet

• The middle of the magnet

• The poles of the magnet

• The edges of the magnet

If a magnet is cut in half, what happens to its magnetic poles?

• Each half retains a single pole.

• Each half becomes a new magnet with both a North and South pole.

• The magnet loses its magnetic properties.

• The poles disappear.
