What does a magnetic field around a long straight wire look like?
Visualize how a compass would react around the wire.
Fleming's Left-Hand Rule helps to determine the direction of what?
Use your hand to visualize it!
A wire is carrying a current of 5 A perpendicular to a magnetic field of strength 0.1 T. Calculate the force on a 0.5-meter section of the wire.
Be careful to use correct units for each variable.
Two wires are parallel and carry currents in the same direction. What happens to the forces they exert on each other?
Think about the magnetic field direction related to each wire.
