Compasses show the direction of the magnetic field around a current in a wire. Iron filings align with the field lines. Place wire and compasses, if desired, under document camera or on projector. If ...
Place wire and compasses, if desired, under document camera or on projector. If using document camera, place sheet of paper underneath for visibility. If using an overhead projector, focus it on the ...
