Magnetic Forces

What do magnetic field lines represent?

• Magnetic field lines indicate the temperature of a magnet.

• Magnetic field lines show the color of a magnetic material.

• Magnetic field lines represent the direction and strength of a magnetic field.

• Magnetic field lines represent the speed of moving charges.

How do magnetic field lines behave around a magnet?

• Magnetic field lines do not form closed loops and only exist in one direction.

• Magnetic field lines are only present at the south pole of the magnet.

• Magnetic field lines emerge from the north pole, curve around, and enter at the south pole, forming closed loops.

• Magnetic field lines only move in straight lines away from the magnet.

What are the two types of magnetic poles?

• East Pole and West Pole

• Positive Pole and Negative Pole

• North Pole and South Pole

• Magnetic Equator and Magnetic Axis

What happens when two like magnetic poles are brought together?

• They attract each other.

• They repel each other.

• They create a magnetic field together.

• They have no effect on each other.

What happens when two opposite magnetic poles are brought together?

• They attract each other.

• They create a magnetic field.

• They remain unchanged.

• They repel each other.

How do magnetic forces affect compass needles?

• Magnetic forces cause compass needles to align with the Earth's magnetic field, pointing towards magnetic north.

• Magnetic forces repel compass needles away from magnetic north.

• Compass needles are unaffected by magnetic forces and point randomly.

• Magnetic forces cause compass needles to spin wildly without direction.

What materials are attracted to magnets?

• Aluminum

• Silver

• Iron, nickel, cobalt

• Gold
