What is the direction of magnetic field Class 10?

Direction of field line: Outside the magnet, the direction of magnetic field line is taken from North pole to South Pole.

Is magnetic field north to south?

Magnetic field lines outside of a permanent magnet always run from the north magnetic pole to the south magnetic pole. The earth spins around the geographic poles, but magnetic compasses point to the magnetic poles.

What is the direction of magnetic moment?

The direction of the magnetic moment points from the south to north pole of the magnet (inside the magnet). The magnetic field of a magnetic dipole is proportional to its magnetic dipole moment.

What is a magnetic compass class 10?

A magnetic compass is a tool from which we can find directions. Explanation. A magnetic compass has a tiny magnetic needle that spins freely. The magnetic field exerts a torque on the needle that pulls the north pole towards the earth’s north magnetic pole and pulling the other towards the earth’s south magnetic pole.

Where is magnetic north right now?

Based on the current WMM model, the 2020 location of the north magnetic pole is 86.50°N and 164.04°E and the south magnetic pole is 64.07°S and 135.88°E.

Why direction of magnetic moment is from south to north?

Considering the current loop as a tiny magnet, this vector corresponds to the direction from the south to the north pole. When free to rotate, dipoles align themselves so that their moments point predominantly in the direction of the external magnetic field.

Is direction of magnetic field and magnetic dipole moment same?

For electric dipole: The direction of the dipole moment is from negative to positive charge, but that of the electrostatic field is from positive to negative. But in the case of magnetostatics, the magnetic field and dipole moment have the same direction.

What is the direction of magnetic field lines in bar magnet?

Magnetic field lines are defined to have the direction that a small compass points when placed at a location. (a) If small compasses are used to map the magnetic field around a bar magnet, they will point in the directions shown: away from the north pole of the magnet, toward the south pole of the magnet.

What is magnetic field Ncert?

The magnetic field is a region or space where there is an influence of a magnet. Bar magnets, rod magnets, horseshoe magnet, ring magnet etc. All types of magnets have two poles; North Pole which is indicated by ‘N’ and South Pole which is indicated by ‘S’. Irrespective of shape every magnet has a field around it.
