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 was proved by the Fr..

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 must also exert an equa..

The lines of force or field lines 1) start from positive charges and end at negative charges. In the case of a single charge, they may start or end at infinity. 2) two field lines can never intersect each other. 3) contract longitudinally. 4) exert lateral pressure on..

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 distance is referred to as magnetic dipole) experience..

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 exerts a magnetic..

. As the hydrogen atoms come closer, the attractive force tends to decrease the potential energy of the system. When the potential energy reaches a minimum value, sharing of electrons take place between the two, resulting in a covalent bond. This stage is represented by the dist..

Gravitational Field - The space around a body within which its gravitational force of attraction is experienced, is called its gravitational field..

The electric field or electric field strength is the electrostatic force acting on a small positive test charge placed at that poin..

Electric Field - The electric field or electric field strength is the electrostatic force acting on a small positive test charge placed at that point. If is the electrostatic force experienced by a test charge q at a point, then the electric fi..

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 distance is referred to as magnetic dipole) experiences a turning force..
