... 4. Decide whether V is positive or negative by considering whether a positive charge would need to be pushed from the initial to the final position (Vfinal > Vinitial), or whether it would be pulled along by the field(Vfinal < Vinitial). Method 2 (Use the Principle of Superposition): 1. Break the g ...

... circulation of a vector field--its tendency to form closed loops. If you think of the velocity field for water flowing in a river, a region with a nonzero divergence contains either a spring (source) of water or a drain (sink). A region of a flowing river with a nonzero curl will cause a paddle whee ...

... Though the net force on a loop of wire in a uniform magnetic field is always zero, a magnetic field can exert torque on a loop of wire. This is given by the equation: t t‚B 7t œ . t is called the magnetic moment. It is defined as follows.: The vector . t is ME, where M is the current, and E is the a ...
