University of Florida - Department of Physics :: PHY2005 Applied ... The force on a wire carrying current I is F = ILBsin(theta), where theta is the angle of the wire with respect to the magnetic field B. Remember that F and B are the magnitudes of the vector force F and the vector field B. For this problem, the theta is 90 degrees, so that sin(90o) = 1.0.

Ch 29 - Magnetic Fields & Magnetic Fields Sources - Polytechnic … • For electric fields, the Fe was parallel to the E field; for magnetic fields, the FB is perpendicular to the B field.! • F B acts only when the charge is in motion.! • FB does no Work on the particle when it’s traveling through a constant B field (because FB and x are perpendicular to each other!).! Currents produce Magnetism?!

Chapter 22 Magnetism - Physics & Astronomy the force is F = ILB (sin theta). (b) The direction of the force is given by the magnetic force RHR; the only difference is that you start by pointing the fingers of your right hand in the direction of the current I. In this case the force points out of the page.
Magnetic Forces and Magnetic Fields - University of Utah In the full electromagnetic theory by Maxwell (not in the scope of this course)...there is a “duality” between electricity and magnetism. The magnetic field, B, like the electric field, is a vector field — a vector valued function of position. Surrounding a magnet there is a magnetic field.

Faraday’s Law - Wake Forest University To counteract this flux, the induced current in the ring has to create a field in the opposite direction. After a few seconds, since there is no change in the flux, no current flows. When the switch is opened again, this time flux decreases, so a current in the opposite direction will be induced to counter act this decrease. ∫ E .
