Magnetism

Question 1

Magnetic field

Answer 1

A region of space where a magnet or a ferromagnetic material will experience a force

Question 2

Domain

Answer 2

A region of an object where the magnetic fields due to individual electrons line up

Question 3

Ferromagnetic

Answer 3

Materials that contain magnetic domains

Question 4

Magnetosphere

Answer 4

A region of space containing the Earth’s magnetic field lines.

Question 5

Domain theory of magnetism

Answer 5

Electrons spin so atoms of iron behave as small magnets with their magnetic fields pointing in all directions. When they become aligned they form small regions of stronger magnetism, called magnetic domains. If all these domains line up in the same direction, the substance as a whole becomes magnetised.
