An electro magnet is formed by a current flowing trough a coil. This induces a magnetic field around the coil. To illistrate the kinetic energy I am going to compare an object of mass (m) moving because of a force (F) in a direction (x) with an electric charge (q) moving trough a circuit with Capcitance (C) and Inductance (L) Speed (v) = rate of change in distance (rate that x changes with time) Current (i) = rate of change in charge (rate that q changes with time) Mass (M) is an indicater of the amount of potential of an object. Inductance (L) is an indicater of the amount of potential of a coil Kinetic energy for an object : E = 1/2 M*v*v Kinetic energy for magnet (Magnetic Enrtgy) : E = 1/2 L*i*i To compare : Mass Inductance Force : F = M*a Position : x Charge : q time : t time : t Speed : v=rate x change pert Current : i=rate q change per t Mass : M Inductance : L Pential energy : Mass : M gravitational conastant : g heigt : x For object E=Mgx (a=g) For Magnet E=1/2*(V/Z)*(V/Z)*L where V = volts R=Resitance of the coil circuit.
