... The equation for magnetic force applies to a charged particle moving through a magnetic field. How would the equation change so that we can apply it to the examples we did earlier using a wire and current? When you look at the units of Tesla it contains a Newton over an Ampere times a meter. Associa ...

... A square loop of side a lies in the x-z plane with current I as shown. The loop can rotate about x axis without friction. A uniform field B points along the +z axis. Assume a, I, and B are known. How much does the potential energy of the system change as the coil moves from its initial position to i ...

... Diamagnetism is the property of an object or material which causes it to create a magnetic field in opposition to an externally applied magnetic field. Unlike a ferromagnet, a diamagnet is not a permanent magnet. Diamagnets were first discovered when Sebald Justinus Brugmans observed in 1778 that bi ...

... Put a rectangular loop of current I and length (height) L, and width w in a uniform magnetic field B. The loop is mounted such that it is free to rotate about a vertical axis through its center. We will consider the forces on each segment and the resulting torque from each. Using RHR-1: The force on ...

The only property of the particle, whose acceleration we are considering on the left hand side of the equation (2), which will actually effect its own acceleration, is the sign of its own electric charge. This will determine the sign beside the Q on the right hand side of equation (2). E ...
