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

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?

• 
• 

What variable from this picture would be your independent variable?

• bolt metal

• bolt length/size

• type of wire

• number of coils

What would be the control in this experiment?

• number of batteries

• number of coils

• number of nails

• none of these

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.

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
