Electromagnetic Induction
... If charges are not constrained to move within a wire, or other conductor, then the force on the charge as it passes through a magnetic field will change its direction of travel. As the force is perpendicular to the velocity (current direction) it alters the direction, but not the speed, of the parti ...

Magnetic flux - Purdue Physics
... magnetic field is passing through a loop of wire. It is at a maximum when the field lines are perpendicular to the plane of the loop, and it is zero when the field lines are parallel to the plane of the loop. For a coil of N loops, the flux through the coil is equal to the flux through one loop, mul ...
