Amplify Magnetic Fields 1.4, 1.5, and 1.6

Front

What types of forces do electric fields and magnetic fields produce?

Back

Both attractive and repulsive forces.

Front

Why does a compass always point north?

Back

The positive north side of the compass magnet is attracted to the magnetic south pole.

Front

What can magnets do to each other?

Back

Magnets can attract or repel each other.

Front

What happens when two like poles of magnets are brought together?

Back

They repel each other.

Front

What is the reason compasses work?

Back

The Earth is a magnet with a molten iron core, which creates a magnetic field around the Earth.

Front

What is the definition of a magnetic field?

Back

A magnetic field is a region around a magnet where magnetic forces can be observed.

Front

What is the difference between magnetic north and true north?

Back

Magnetic north is the direction a compass points, while true north is the direction along the Earth's surface towards the North Pole.

Front

What is the role of the Earth's molten iron core in its magnetic field?

Back

The molten iron core generates the Earth's magnetic field through its movement.

Front

What is the principle behind the operation of a compass?

Back

A compass operates on the principle that a magnetized needle will align itself with the Earth's magnetic field.

Front

What are the two types of magnetic poles?

Back

North pole and south pole.
