List 4 ways you can strengthen a electromagnet.?

what is your last name. because a girl in my grade is melissa S and the weird thing is that i have to answer the same question you are asking due on the same day as yours. Oh and to answer your question a few ways are by adding more current to the wire, coiling the wire as many times as possible around the core and as tightly together as possible. You can also use a larger ferromagnetic core or

you can have a wire with less resistance (Smaller gauge such as 1 or 2).

Ways to increase the magnetic field of an electromagnet:- 1 . By increasing the number of turns of winding in the solenoid.2 . By increasing the current through the solenoid

I think u may put an soft iron rod, cobalt rod, or Nickel rod in the center of the solenoid. Number of turns on the solenoid must be increased to an appropriate number.

Have more coils going around and it also increases if you place an iron core going through the center.
