Question

HOW CAN A MAGNETIC FIELD BE PRODUCED WITHOUT USING A MAGNET

Answer 1

When current passes through a wire or a conductor then it creates an electromagnetic field which this helps in creating magnetic field.

Answer 2

A Magnetic field can be produced without using a magnet through an electromagnet or a current-carrying conductor.

Explanation:

• A magnetic field is described as a condition in the space around a magnet in which there is a detectable magnetic force and two magnetic fields are present.
• As per the experiment of Oersted, we learn that by passing the current across a conductor one can produce such a field.
• Thus, an electromagnet will act as a magnet that will display similar properties and form a magnetic field and attract the metals when it is electrically activated. However, the strength of the magnetic field will depend on the enormity of the current and the number of circuits of the current.
