Question

Which of these is not a source of magnetic field?

(a) magnet (b) moving charges (c) electric current (d) battery​

Answer 1

Answer:

Current-carrying conductors

Explanation:

An electric current produces a magnetic field. This magnetic field can be visualized as a pattern of circular field lines circling a wire.

Answer 2

The right option in context to this question is option d: battery.

• A field of a magnet is an area or region where any other item, depending on its nature, experiences an attractive or repulsive force.
• The magnetic field is an attribute of magnets.
• It's also a characteristic of moving charges.
• The correct source of the magnetic field is a magnet.
• A magnetic field is produced by particles that are charged and are in motion.
• Because electric current has charges moving in a conductor, it produces a magnetic field.
• Because it has a stored electric charge that is static, Battery is not a source of the field.
• As a result, option d isn't the right source.
