Electric fieldsare generated around particles that bear electric charge. Positive charges are drawn towards it, while negative charges are repelled.
The area around a magnet within which magnetic force is exerted, is called a magnetic field. It is produced by moving electric charges. The presence and strength of amagnetic fieldis denoted by “magnetic flux lines”. The direction of the magnetic field is also indicated by these lines.
Difference:
(a) An electric field is a field of force, surrounding a charged particle, while a magnetic field is a field of force surrounding a permanent magnet, or a moving charged particle.
(b) The strength of an electric field is expressed in Newtons per Coulomb, or Volts per meter, while a magnetic field strength is expressed in Gauss or Tesla.
(c) The force of an electric field is proportional to the electric charge, while the magnetic field is proportional to the electric charge as well as the speed of the moving charge.
(d) Electric and magnetic fields oscillate at right angles to one another.

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
