A field model can be used to explain how two objects can exert forces on each other without...

Objects are thought to have a region of influence surrounding them. This region is also called a

What is a magnetic field?

• A type of field that surrounds stationary electric charges.
• A type of field that only surrounds magnets.
• A type of field that repels magnets and electric charges.
• A force field that surrounds magnets and moving electric charges.

When a object 1 is in the region of influence of object 2, the field exerts a force on object 1 and it...

• does not experience a force

• moves

• moves away from object 2
• attracts object 2

What is a permanent magnet?

• A material that produces a magnetic field and retains its magnetism over a long period of time.
• A material that does not produce a magnetic field but retains its magnetism over a long period of time.
• A material that produces a magnetic field but only temporarily retains its magnetism.
• A material that produces a magnetic field but loses its magnetism quickly.
