A student built a simple electromagnet with copper wire, an iron bolt, and a 1.5-volt battery. The electromagnet was able to lift a paper clip from 3 centimeters away. Select THREE ways the student can increase the strength of his electromagnet.
1. Increase the number of turns in the copper wire coil. This will increase the magnetic field strength produced by the electromagnet.
2. Use a stronger battery with a higher voltage. Increasing the voltage will increase the current flowing through the wire coil, thus increasing the magnetic field strength.
3. Use a larger and/or denser piece of iron as the core of the electromagnet. A larger and denser core will concentrate and amplify the magnetic field produced by the wire coil, resulting in a stronger electromagnet.
A.
He can use a thicker piece of copper wire.
B.
He can reverse the orientation of the battery.
C.
He can replace the iron bolt with a wooden rod.
D.
He can add a switch between the battery and the iron bolt.
E.
He can replace the 1.5-volt battery with a battery of higher voltage.
F.
He can use a longer piece of wire that wraps more times around the bolt.
Among the options given, the three ways the student can increase the strength of his electromagnet are:
E. He can replace the 1.5-volt battery with a battery of higher voltage.
F. He can use a longer piece of wire that wraps more times around the bolt.
A. He can use a thicker piece of copper wire.

Apologies for the confusion in the previous response. Let me correct the choices:
The three ways the student can increase the strength of his electromagnet are:
1. He can use a thicker piece of copper wire.
2. He can replace the 1.5-volt battery with a battery of higher voltage.
3. He can use a longer piece of wire that wraps more times around the bolt.
