Question

A current carrying loop lying in a magnetic field behaves like a:
A. Magnetic dipole
B. Magnetic pole
C. Magnetic material
D. Non-magnetic material

Answer 1

Hint: Magnetic field can be produced in a loop by applying electric current.

Complete step by step answer:

A loop starts producing a magnetic field when electric current is applied to it. The magnetic field is produced in the term of concentric circles at every point of the current carrying circular loop. The direction of the magnetic field is given by the right hand thumb rule: It states that, if we note the fingers of a right hand in a circular form and sketch out thumb out. Then the direction of thumb given the direction of current and the direction of fingers gives the direction of magnetic field lines.
If we add multiple loops and form one current carrying loop with n small loops, where n is the number of small loops added. Then there would be a magnetic field produced by each loop. In this case, though it looks like an electric dipole, it would behave as a magnetic dipole present in the magnetic field.
Therefore, from the above explanation the correct option is (A) Magnetic dipole.



Note:Electric dipole: An electric dipole is defined as a couple of opposite charges $ + q$and $ - q.$Separated by a small distance . All magnets have magnetic north and south poles. We call them dipoles. It is impossible to create a magnet with only one pole.
