Electromagnetism

How do you make a permanent magnet?

• Manipulate a ferromagnetic metal so that all the domains are unaligned

• Manipulate a ferromagnetic metal so that all the domains are aligned

• Manipulate a ferromagnetic metal so that all the domains are pointing randomly

• Magic

What would happen if you cut a magnet in half?

• You would create two smaller magnets

• You would cause the magnet to stop functioning as a magnet

• You would create two polarized half-magnets (one north piece and one south piece)

• Half would be a magnet and the other half would stop being a magnet

Magnetic fields flow:

• From the magnetic south pole to the magnetic north pole

• From the magnetic north pole to the magnetic south pole

• From the magnetic north pole back to the magnetic north pole

• From the magnetic south pole back to the magnetic south pole

When a charge enters a magnetic field, the magnetic force on the charge is at its maximum value when:

• The charge enters parallel to the field

• The charge enters the field at a 45 degree angle

• The charge enters perpendicular to the field

• The angle is irrelevant
