magnetic field of a bar magnet at an axial point
Answers
Magnetic field is defined as the space around a magnet over which its influence is experienced and can extend up to infinity.
Magnetic induction is a vector quantity.
All magnetic objects produce invisible lines of force that extend between the poles of the object.
Magnetic field lines originate from the north pole and terminate at the south pole. They form close and continuous loops extending through the body of the magnet.
Two magnetic field lines can never intersect each other. The tangent to magnetic field lines at any point gives the direction of magnetic field intensity at that point.
The magnetic field due to a short bar magnet at any point on the axial line is twice the magnetic field at a point on the equatorial line of that magnet at the same distance.
S.I. unit of torque acting on the bar magnet is Nm.
Potential energy of a magnetic dipole in a magnetic field is the energy possessed by the dipole due to its particular position in the field.
The flux associated with a magnetic field is a measure of the number of magnetic field lines penetrating some surface.
Gauss’s law in magnetism states that the surface integral of magnetic field, due to a magnetic dipole enclosed in a surface, taken over the closed surface is zero.
Gauss’s theorem in magnetism establishes that isolated magnetic poles do not exist.
A magnet is a material or object that produce the magnetic field .
Explanation:
The magnetic field due to the bar magnet at any points on the Axial lines is twice the magnetic field of the magnet at the same distance .
