Do Wow-2,-21-25: How do electromagnots change the neversals of 2 -anths magnefic field over fime?

Electromagnets change the intensity of a magnetic field over time by altering the flow of electric current through the coil of wire that makes up the electromagnet. When the current flows through the coil, it generates a magnetic field. By increasing or decreasing the current, the strength of the magnetic field can be adjusted. Additionally, the orientation of the coil can also be changed to alter the direction of the magnetic field.
