Magnetic Effect...

The magnet is strongest near the

The diagram below shows a wire carrying conventional current in the direction shown by the red arrows.
The magnetic field is straight downward, as indicated by the blue X's.
What is the direction of the force exerted by the magnetic field on the wire?

A straight wire carries current toward the east.
What is the direction of the magnetic field directly below the wire?

A straight wire carries conventional current toward the sky.
What is the direction of the magnetic field due to the current at a point west of the wire?

As a negatively charged bowling ball rolls eastward toward some bowling pins, in what direction does it experience a force, due to the earth's magnetic field (Assume the earth's field is pointing straight north)?

All of the following magnets pictured have magnetic field lines like the ones pictured in the diagram above. For which one are the poles correctly labeled?

An electron enters a magnetic field directed to the right, with a velocity toward the bottom of the screen. What is the direction of the force on the electron?

In alternating current:

Energy in a current - carrying coil is stored in the form of :
