anyone has moving charges and magnetism notes? class 12
Answers
Answer:
Electric charges and magnetism similar
Just as the positive (+) and negative (−) electrical charges attract each other, the N and S poles of a magnet attract each other. In electricity like charges repel, and in magnetism like poles repel.
Answer:
During a lecture demonstration in 1820, the Danish physicist Hans Christian Oersted noticed that a current in a straight wire caused a noticeable deflection in a nearby magnetic compass needle. He further investigated this phenomenon and confirmed the phenomenon of magnetic field around current carrying conductor.
Magnetic Field
It is the space around a magnet or current carrying conductor around which magnetic effects can be experienced. It is a vector quantity and its SI unit is tesla (T) or Wbm‒2
Moving Charge & Magnetic Field
A charge can produce magnetic field if it is in motion. Magnetic field can also interact with a moving charge.
Lorentz Force
Assume a point charge q (moving with a velocity v and, located at r at a given time t) in presence of both the electric field E (r) and the magnetic field B (r).
hope this help you.
feeling good to help you.
