Force on a Current Carrying Wire
What do electrical currents have to do with an MRI? Using a simple wire setup and a magnet, class members explore forces used in an MRI by investigating the magnetic force acting on a wire carrying a current.

Thrown for a Loop
Round and round it goes. Class members observe a current carrying loop in a magnetic field and calculate its associated torque. They then apply what they have learned to example problems to solve for the torque and to calculate the...
