How Magnets Interact

​The electric or magnetic force from a body or particles that draws another towards it; the force holding the particles together.

​​Attract (attration)

​To force (something) to move away or apart

​​Repel (repulsion)

Multiple Choice

Which statement is true?

• The top magnets show repulsion and the bottom magnets show attraction

• The top magnets show attraction and the bottom magnets show repulsion.

​Magnetic field lines emerge (start) from the North pole outside the magnet.

​​North: Magnetic Pole

​Magnetic field lines end at the South pole outside the magnet.

​​South: Magnetic Pole

Multiple Select

Select the true statements.

(There are 2)

• Magnetic Field lines start at the North Pole

• Magnetic Field lines end at the North Pole

• Magnetic Field lines start at th South Pole

• Magnetic Field lines end at the South Pole

​Opposite poles attract each other.

​​Attract (attration)

​Like poles repel each other.

​​Repel (repulsion)
