The easiest way it to stick it to a metallic surface and then apply an increasing force to pull it with a device that measures the force applied, until the magnet disconnects from the surface.
If it follows the 1st law of thermodynamics it would also remove heat of 314J from the food inside the refrigerator.
Answer:110v
Explanation:
Current=100 amperes
Resistance=1.1 ohms
voltage=current x resistance
Voltage=100 x 1.1
Voltage=110v
