What is an insulator?

• A material that DOES NOT allow electric current to flow

• A material that DOES allow electric current to flow

How is electricity a force?

• It is not a force

• Electrons are pushed through a circuit

• Protons are pushed through a circuit

• Neutrons are pushed through a circuit

How are electromagnets different from regular magnets?

• Their strength can be changed

• They can be turned on and off

• Their polarity can be reversed

• All choices are correct

Which magnet would be aligned correctly on this picture of Earth?

• 
• 
• 
• none of these

So this means that the North Pole is really the "Southern" end of the magnet of Earth?

How do these desk toys work when nothing is touching?

• like magnetic fields are still exerting similar forces

• opposite magnetic fields are attracting the object

• no forces are at work because there is no contact

• the objects float because there are like and unlike forces acting on each other

Is the "length of wire" noted anywhere that it will have any effect on an electromagnet experiment such as this one?

More coils of wire will produce a stronger magnetic force, which also means a stronger magnetic field.

Which question is BEST answered by the data shown in the data table?

• How does kinetic energy affect the distance an object can go?

• How does mass affect the kinetic energy of an object?

• How does mass make an an object move?

• How does gravity change the mass of an object?
