Question

what happens to the strength of the electromagnet when the magnitude of current decreases ?​

Answer 1

Answer:

Battery Current

Changing the amount of current flowing through the electromagnet will also change the field the it produces. The greater the current in the coil, the stronger the magnetic field will grow. Conversely, lowering the battery voltage decreases the current, weakening the field.
