Using Ohm's Law (V = I * R), where V is voltage, I is current, and R is resistance, we can rearrange the formula to solve for resistance: R = V / I. In this case, R = 12V / 0.5A = 24 ohms. So the resistance of the electromagnet is 24 ohms.

An electromagnet operator can release metal attached to the electromagnet by turning off the electric current flowing through the electromagnet coils. This de-energizes the electromagnet, causing the magnetic field to dissipate and the metal object to fall off.
