Question

Give Formula of magnetic dipole moment of Circular Coil Carrying current.​

Answer 1

The dipole moment of a circular loop carrying a current I , is m and the magnetic field at the centre of the loop is B1. When the dipole moment is doubled by keeping the current constant, the magnetic field at the centre of the loop is B2. The ratio B1B2 is: (A) √2.

• The magnetic dipole moment of the current loop is equal to the product of ampere-turns and area of current loop.

• The magnetic dipole moment of the current loop is equal to the product of ampere-turns and area of current loop.

• vector quantity that is a measure of the torque exerted on a magnetic system (such as a bar magnet or dipole) when placed in a magnetic field and that for a magnet is the product of the distance between its poles and the strength of either pole.

• The substance which contains species with unpaired electrons in their orbitals behave as paramagnetic substance. The paramagnetic is expressed in terms of magnetic moment. The Magnetic moment of an atom. μs=s(s+1) 2πmceh=2n(2n−1) 2πmcehs=2n

• Ampere found that the distribution of magnetic lines of force around a finite current-carrying solenoid is similar to that produced by a bar magnet. A planar loop of any shape behaves as a magnetic dipole. ... The dipole moment of current loop ampere turns (nI) area of coil (A)

• Definition. It can be defined as a vector linking the aligning torque on the object from an outside applied a magnetic field to the field vector itself. The relationship is written by. tau=m×B. Where τ is the torque acting on the dipole, B is the outside magnetic field, and m is the magnetic moment.

• For example, ammonia (NHsub3) is a polar molecule. As you can see, ammonia consists of one nitrogen atom covalently bonded to three hydrogen atoms. ... The presence of both a positive and negative charge on the molecule means that ammonia is polar and, therefore, exhibits a net dipole moment.

Answer 2

Answer:

The formula of the magnetic dipole moment of circular coil carrying current is, m = nIA

Explanation:

• A magnetic moment also referred to as a magnetic dipole moment, is a measurement of an object's tendency to align with a magnetic field.
• The magnetic pull and direction of a magnet or other item that generates a magnetic field are known as the "Magnetic Moment" A vector quantity is a magnetic moment.
• The vector whose magnitude is equal to the area of the loop times the magnitude of the current flowing through it (m = IA) and whose direction is perpendicular to the plane in which the current flows is the magnetic moment m of a current loop.
• It is mathematically expressed as- m = nIA where n is the number of loops, I is current and A is the area
• ∵ The area of the circle is πr²
• Therefore, the Magnetic moment becomes, m = nIπr²

Thus, The formula of the magnetic dipole moment of circular coil carrying current is, m = nIA
