Force Acting on a Current-Carrying Conductor in a Magnetic Field - Oersted's experiment shows that a current carrying wire exerts a force on a magnetic needle and deflects it from its usual north-south position. The reverse must also be true, which ..

Oersted's experiment shows that a current carrying wire exerts a force on a magnetic needle and deflects it from its usual north-south position. The reverse must also be true, which was proved by the French scientist Andre Marie Ampere, who suggested that a magnet mus..

A magnetic field is defined as a region in which a magnetic force is present. In a magnetic field, the magnetic dipole (two equal and oppositely charged or magnetized poles separated by a distance) experiences a turning..

It can be either attractive or repulsive. It can be the force between two magnets or force on a magnet placed in a magnetic field..

Magnetic Field - Magnetic field is a region near a magnetised body where magnetic forces can be detected. In a magnetic field, the magnetic dipole (Two equal and oppositely magnetised poles separated by a dist..

If a small compass needle is placed at a point near the north pole of a bar magnet, the needle turns round on its pivot and settles in a fixed direction as shown in figure. At other points away from the pole the needle settles tangent to the field lines shown. The magnet..

Magnetic lines of force form closed continuous curves. Outside the body of the magnet, their direction is from north to south pole. The tangent to these lines at any point gives the direction of the magnetic field at that point. No two li..

>These points form a curve The curved line represents a magnetic field line or magnetic line of force Repeat the above procedure and draw as many lines as you c..

The earth's magnetic field has an axis which is inclined 20 o west of the axis of rotation of earth. The point where this huge earth's magnet cuts the earth's surface are the magnetic poles. A freely suspended magnet has its north pole pointing towa..

A solenoid is a long coil (shaped like a cylinder) containing a large number of close turns of insulated copper wire. The figure above shows a solenoid SN whose ends are connected to a battery B through a switch X. When a current is passed through a solenoid, it produces a magnetic ..
