Question

Suggest one way to strengthen the magnetic field in the electromagnet.

Answer 1

Hint: We know that strength of the magnetic field is directly proportional to the magnitude of current flowing through it.
A solenoid has more magnetic field strength than a simple coil.

Complete step by step answer:
In the given question, we are asked to strengthen the magnetic field in the electromagnet.
We know, by the current flowing into the wire, the intensity of the magnetic field generated in the electromagnet, can be increased. The increase in the number of turns on the electromagnet is another way to increase the magnetic field.

Some other ways to strengthen the magnetic field are:
1. Wrap a piece of iron (such as an iron nail) around the coil.
2. The coil adds more twists.
3. The current flowing through the coil rises.

Additional Information:
Magnetic field: A magnetic field is a vector field that determines the magnetic effect on electrical charges, electrical currents, and magnetized materials that pass. A force perpendicular to its own velocity and to the magnetic field is encountered by a charge travelling in a magnetic field.

Electromagnet: An electromagnet is a type of magnet in which an electric current generates a magnetic field. Normally, electromagnets consist of a wire wound into a coil. A current through the wire induces a magnetic field that, denoting the coil core, is concentrated in the hole.

Note:
- A benefit they have over permanent magnets is the flexibility of electromagnets. Adjustable strength, greater control over the magnetic field, and longevity are factors leading to the flexibility of electromagnets.
- A force perpendicular to its own velocity and to the magnetic field is encountered by a charge travelling in a magnetic field.
