Malik 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 Malik can improve the strength of his 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 rod with a wooden rod.
d
He can replace the 1.5-volt battery with a battery of higher voltage.
e
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.
d. He can replace the 1.5-volt battery with a battery of higher voltage.
e. He can use a longer piece of wire that wraps more times around the bolt.
Using a thicker wire will reduce the resistance in the circuit, allowing more current to flow and increasing the strength of the magnetic field. Increasing the voltage of the battery will increase the current and consequently, the strength of the magnetic field. Using a longer wire that wraps more times around the bolt will also increase the number of turns in the coil, resulting in a stronger magnetic field. Reversing the orientation of the battery and replacing the iron rod with a wooden rod will not have a significant impact on the strength of the electromagnet.
The three ways Malik can improve the strength of his electromagnet are:
1. Use a thicker piece of copper wire (option a): The strength of an electromagnet is directly proportional to the amount of current passing through the wire. Thicker wire has lower resistance, allowing more current to flow and thus increasing the strength of the electromagnet.
2. Use a longer piece of wire that wraps more times around the bolt (option e): Increasing the number of wire turns around the iron bolt creates a stronger magnetic field. As more loops of wire are added, the magnetic field strength adds up, resulting in a stronger electromagnet.
3. Replace the 1.5-volt battery with a battery of higher voltage (option d): The strength of an electromagnet depends on the current passing through the wire. A higher voltage battery will provide more potential difference and drive more current through the wire, resulting in a stronger electromagnet.
So, the three ways Malik can improve the strength of his electromagnet are to use a thicker piece of copper wire, use a longer piece of wire that wraps more times around the bolt, and replace the 1.5-volt battery with a battery of higher voltage.
The three ways Malik can improve the strength of his electromagnet are:
a) He can use a thicker piece of copper wire.
e) He can use a longer piece of wire that wraps more times around the bolt.
d) He can replace the 1.5-volt battery with a battery of higher voltage.
