Right Hand Rule Practice
Right Hand Rule #1: Moving Charge
An electron moving in a uniform magnetic field will travel in a circle. Using the right
hand rule, show that this is true. Make eight “measurements” (N, NE, E, SE, S, SW, W,
NW). At the location of each measurement, draw one arrow that shows the direction of
the electron’s velocity and one that shows the direction of the force acting on the
electron. The magnetic field should point into the page and the electron should move in
the plane of the page.
Right Hand Rule #1: Current
Two magnets are positioned next to each other, as shown below. A current-carrying wire
runs between the magnets. In which direction must the current flow in order for the wire
to feel a force in the following directions. You must first determine the direction of the
magnetic field between the magnets.

What happens if you try to apply the right hand rule to a current that is moving left to
right or right to left? What do you think this indicates about the magnetic force?
Right Hand Rule #2: Current Carrying Wire
Position the wire so that it points towards/away from you. Apply the right hand rule for
both the case where the current runs towards you and away from you. Draw the current
and associated magnetic fields below.
Now positions the wire so that it runs across your desk from left to right. If the magnetic
field appears to be directed clockwise, as seen by an observer standing near the blue
board, in what direction is the current running?
Right Hand Rule #3: Solenoid
Wrap the wire loosely around a pencil or pen, as Mr. Marsh does, creating a solenoid. If
the current is to move left to right across the pencil, in which direction is the north pole of
the solenoid facing?
If the current is running clockwise as seen by the observer near the blue board, in which
direction is the north pole of the solenoid facing?
