Which is true of magnetic field lines but not electric field lines

Which converts mechanical energy to electrical energy
a generator
Electric fields and magnetic fields are both present near a wire carrying current
true
When a wave moves from a dense medium to a less dense medium most of the wave energy is
refracted
According to Coulombs Law how does distance affect the electric force
electric force can act at a distance bbut is stronger when object are closer
Any magnetic properties occur
at the atomic level because of the movement of electrons
When none of the magnetic domains in a material will stay aligned the material is called
not magentic
In a closed circuit what does an increase in voltage cause
an increase in current, hence increased power and increased heat.
What will be attracted to or repelled by an magnet
