Q.

The force between two magnetic poles is F. If the distance between the poles and pole strengths of each pole are double, then the force experienced is

Q.

A wire of length L meter carrying current i ampere is bent in the form of a circle. What is the magnitude of magnetic dipole moment?

Q.

A current carrying loop is placed in a uniform magnetic field in four different orientations, I, II, III and IV, arrange then in the decreasing order of potential energy

                                                

Q.

A short bar magnet placed with its axis at  with a uniform external magnetic field of 0.16 tesla experiences a torque of magnitude 0.032 J. The magnetic moment of bar magnet will be

Q. What is magnetic induction? What is difference between elelectromagnetic induction and mag induction?

Electromagnetic induction is the production of an electromotive force across a conductor when it is exposed to a varying magnetic field

Q. Define the term 'Permeability of Vaccum' ?

(General Physics) the permeability of free space, which has the value 4π × 10-7 henry per metre. Symbol: M0 Also called: absolute permeability The permeability of free space is the ratio between magnetic displacement and magnetic field strength (in a vacuum

Q. State the rule that is used to find the direction of field acting at a point near a current carrying straight conductor. ?

This has been explained in the video please have a look at it.

Q. what is actually AC CURRENT&DC CURRENT in simple words?

Direct current (DC) is the unidirectional flow of electric charge. Direct current is produced by sources such as batteries, thermocouples, solar cells, and commutator-type electric machines of the dynamo type. Direct current may flow in a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). n alternating current (AC, also ac), the flow of electric charge periodically reverses direction

Q. sir could u tell me which book is gud for solving JEE mains and advanced for physics which has guidance to all the given questions at the end of every of every chapter?

arihant and use kaysons new feature 'make me iitian'

Q. Please give me a sample of a routine for studying physics for iit as well as boards?

study each subject 4 hrs daily.but important is that how much you understand its concept.in iitjee,concept of topic is very important
