When would a wire carrying electric current experience zero magnetic force when placed in a strong magnetic field?
When the current flows parallel or opposite to the field.
When the current flows at a 30o angle to the field.
When the current flows perpendicular (at a 90o angle) to the field.
How would a piece of metal that can become an induced magnet behave when placed near a permanent magnet?
It will not be attracted to the permanent magnet.
It will be attracted to one side of the permanent magnet but repelled by the other.
It will be attracted to both sides of the permanent magnet, no matter how you place it.
It will only be attracted to the permanent magnet when current is running through it.
It two parallel wires carry current in opposite directions, where will the magnetic field be strongest?

To the right of the right wire only.
To the left of the left wire and to the right of the right wire.
In the region between the two wires.
Where on the Earth's surface is the magnetic field the strongest?
