Answer:
the amount of current flowing through the wire
the number of coils in the wire
the material of the core
Explanation:
When current is passes through a coil, it generates magnetic field. This forms an electromagnet. The strength of the magnetic field generated by an electromagnet can be controlled. It depends on the following factors:
- Number of coils in the wire
- Amount of current flowing in the coil
- The material which forms the core
B = μ n I
where μ is the permeability, n is the number of turns in the wire and I is the current.
The strength increases with in number of coils and amount of current.
Other than this, the magnetic field strength increases if the core is made of magnetic material such as Iron.
The following factors affect the strength of an electromagnet
1. The direction of the current flowing through the wire.
2. The amount of current flowing through the wire
3. The number of coils in the wire the material of the wire.
4. The material of the core.
What is an electromagnet?
An electromagnet is a magnet where the electric current is due to the electric current passes through the coil wound on the material.
The factors that affect the strength of an electromagnet can be simply understood by the formula below.
B = μ n I
μ stands for permeability.
n is the number of turns in the wire.
I stand for the current.
B stands for the megentic field .
The above formula shows that the magnetic field is directly proportional to the permeability, the no of turns on the wire, and the current flowing in the electric wire.
