Detailed Solution for Test: Magnets - Question 1
Maglev (stands for magnetic levitation) trains use this idea to lift them off the ground
Test: Magnets - Question 2

Which one of the following groups of metals are attracted to a magnet?

Detailed Solution for Test: Magnets - Question 2

Steel, iron, and nickel are metals that are attracted to a magnet and are considered ferromagnetic. Ferromagnetic materials have strong interactions with magnetic fields, causing them to be attracted to magnets. Copper and gold, on the other hand, are not attracted to magnets and are classified as non-magnetic materials in this context.

It lines up with the magnetic field of the Earth
Test: Magnets - Question 8

Which type of magnet retains its magnetism after being removed from a magnetic field?

Detailed Solution for Test: Magnets - Question 8

Permanent magnets are materials that retain their magnetism after being magnetized. They can produce their own persistent magnetic fields without the need for external stimulation.

Test: Magnets - Question 9
The ends of a bar magnet are called .......
Detailed Solution for Test: Magnets - Question 9
Magnetic force is strongest at the poles
Test: Magnets - Question 10

How can you demagnetize a magnet?

Detailed Solution for Test: Magnets - Question 10

Demagnetization can occur by exposing a magnet to a strong magnetic field in the opposite direction to its magnetization. This disrupts the alignment of the magnetic domains within the material, thereby reducing or eliminating its magnetic properties.
