outside a magnet magnetic field lines are conventionally drawn from

Magnetic Fields and Field Lines - 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 nee..

Magnetic field is a region near a magnetised body where magnetic forces can be detecte..

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 directio..

The compass needle always lies along the direction of the field. The figure below shows the lines or pattern of the field, when the compass needle is placed at several places. These lines do not really, tell us the effect that magnet has on the othe..

Magnetic Field Lines Due to a Current in a Straight Conductor - We need to understand the pattern of field lines around a straight conductor carrying current and also the direction of these field lines. Here is an experiment to m..

Magnetic Field Due to a Solenoid - 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 thro..

Rules for Determining the Direction of Magnetic Field - The direction of magnetic field around a current carrying conductor can be determined by using one of the laws given here. Rule Pictorial Representation Right Hand Thumb Rule Imagine that you are holding..

Consider a point P located on the axial line of a short bar magnet of magnetic length '2l' and pole strength m. Let us find at a point p which is at a distance d from the centre of the magnet. Magnetic flux density at p due to N-pole ..

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 force, wh..

We need to understand the pattern of field lines around a straight conductor carrying current and also the direction of these field lines. Here is an experiment to map the magnetic field lines. Procedure Observatio..
