Solution

The correct option is C Use a multimeter to calculate the current flowing through the coil
Check the amount of current flowing through the electromagnetic coil. Use a multimeter to do this. The stronger the current, the stronger the magnetic field generated. Ampere-turn per meter is another metric unit for measuring magnetic field strength. This represents how if the current, the number of coils, or both are increased, the magnetic field strength increases.
