Magnetic Force on a Moving Charge
4) For charges of opposite sign the force acts in a direction opposite to that of positive charges..
Moving Charges and Magnetism Summary
e is the net, current enclosed by the closed circuit. Employing Ampere's law one can show that the magnitude of the field B inside a long solenoid carrying a current i is B = m 0 ni where n is the number of turns per unit length. For a toroid one obtains, where N is the tota..

Introduction - The branch of physics which deals with magnetism due to the electric current is called electromagnetism. For a long time it was hard to believe if there existed a relation between electricity and magnetism..
Electricity, Heating, Magnetic Effects Summary
Summary - Electric potential is the condition that determines the flow of charge. Electrical potential at a point in an electric field is defined as the amount of work done in bringing a unit of positive charge from infinity to that point...
Mapping of Magnetic Lines of Force
Mapping of Magnetic Lines of Force - A pictorial representation that gives the direction of the magnetic field at various points in a magnetic field is called a map of the magnetic field Let us now map the magnetic..

Even though I don't feel good, the tutor helped me by totally helping me understand!
The tutors are amazing. They are very committed in helping students solve the questions and explains all the steps beautifully. So 5 stars for Tutor Vista.
Tutor Vista tutors are pleasant and great to work with, they were very patient and explained everything that is simple to follow. I love working with them. - John Coakley
My son really liked the tutors approach! thanks so much he left the computer feeling postive and confident about his test tomorrow. and that make us (mom and dad) happy!!!!!!
