Solution

The correct option is D All
Can add second battery to increase the amount of current. Add more number of turns in the coil. In addition, an electromagnet also depends on the type of core used. Type of material, shape, size and winding pattern of the coil also control the shape and strength of the magnet field of an electromagnet.
