Moving Charges and Magnetism Summary
Summary - The Biot-Savart law asserts that the magnetic field dB due to an element dl carrying a steady current i at a point P at a distance r from the current element is: The constant m 0 has the exact value m 0 = 4 p x 10 - 7 T m A - 1 It is the permeability of free space. It ..

We have seen in the previous lesson that a current carrying conductor when kept in a magnetic field experiences forces and torque..
Electromagnetic Induction
Electromagnetic Induction - Michael Faraday the English scientist was the first person to prove that a magnet can create a current To test this he moved a magnet towards and away from the coil of wire connected to a galvanometer He observed that there was a deflection ..

Self Induction - When a current is established in a conductor, a magnetic field is produced in its vicinity. We can visualize this field in terms of magnetic flux. If steady current flows the number of lines of force at a given place would remain the same. But if the c..

Whenever the amount of magnetic flux linked with a circuit changes, an EMF is induced in the circuit. This induced EMF lasts so long as the change in magnetic flux continues. EMF induced in a circuit is directly proportional to the rate of change of magnetic flux lin..

very helpful of a complex problem, oh my god I would have never completed this problem with out the tutor. Tutor vista thank u so much.
I need tutoring from tutorvista till th end of my schooling. Tutors are not only experts they are brilliant enough to make a student like me understand the concepts of differentiation and functions.
The tutor remembered me from last week and noted my improvement. This is simply amazing :)
My daughter use to study from personal tutor for Maths, but now when she is studying through TutorVista, she gets tutoring for Maths, Science, English.. everything at a price cheaper than the Math tutor she had.
Looking for More Help!
