Final answer:

To increase the strength of an electromagnet, you can add more coils, increase the current passing through the wire, and use a ferromagnetic core.


Explanation:

The strength of an electromagnet can increase by either:

  1. Adding more loops (coils) of wire around the core.
  2. Increasing the current passing through the wire.
  3. Using a ferromagnetic core like soft iron inside the coil to concentrate the magnetic field, thus increasing its strength.

These methods enhance the magnetic field generated by the solenoid, making the electromagnet stronger.
