Does a current loop behave as a magnetic dipole?

Complete step by step answer Current loop as a magnetic dipole behaves like a magnet. It has magnetic field lines as well as north and south poles just like a bar magnet.

Can a current loop be treated as dipole moment?

When current flows in a loop and is suspended freely it stays along north-south direction,. So it behaved as a magnetic dipole of magnetic moment ‘m’ amp-m2.

Can a current carrying loop be treated as a magnetic dipole explain?

Looking at the upper face, current is anticlockwise and , therefore , it has a north polarity. Looking at the lower face of the loop, the current is clockwise and hence it has a south polarity. The current loop, thus, behaves as a magnetic dipole.

Why is a current loop considered as a magnetic dipole?

At the lower face of the loop, the current being flowing loop thus behaves as a sy magnetic dipole clockwise, it will behave as magnetic south pole. The current carrying stem of two equal and opposite magnetic poles and hence is a magnetic dipole.

How current loop behaves as a magnetic dipole calculate the dipole moment associated with it?

When x >>R, (i.e at a long distance from O along the x-axis), here m = NIA called Magnetic dipole moment of the loop and A = R2, the circular area of the loop. here pe is the electric dipole moment. This shows the current carrying circular loop is equivalent to a magnetic dipole.

Why is current considered as magnetic dipole?

Why does current carrying loop act as a magnet?

A current carrying loop creates a magnetic field around it. The strength of the magnetic field created depends on the current through the conductor. At the centre of the loop the magnetic feild lines are perpendicular to the plane of the loop and behaves like a magnet.

How do you determine the direction of a magnetic dipole?

The direction of magnetic dipole moment is from south pole to north pole of a bar magnet. Considering the current loop as a tiny magnet, this vector corresponds to the direction from the south to the north pole.

What is the relationship between the current and the magnetic moment of a current carrying circular loop?

Answer- The dipole moment of a circular loop carrying current is the dipole moment of a bar magnet which creates same magnetic field around as the loop does. It is found that the magnetic dipole moment of the current carrying loop is directly proportional to the current and the area of the current loop.

What is magnetic dipole moment in physics?

The magnetic dipole moment, often simply called the magnetic moment, may be defined then as the maximum amount of torque caused by magnetic force on a dipole that arises per unit value of surrounding magnetic field in vacuum.

How does a current carrying loop behave as a bar magnet?

A current loop behaves as a bar magnet because (i) one face of current loop behaves as a south pole and the other face as north pole. (iii) it experiences a torque in an external magnetic field, which tends to align the axis of the loop along the direction of magnetic field as bar magnet does.
