We are introduced to the magnetic field as a way to keep track of the force that arises from lenght contraction in special relativity. A moving distribution of charge becomes more dense in the right frame. So in a way, the magnetic field is just the E-field. However, when I glance over the physics of permanent magnets, it is said that their magnetic field arises from the integral sum of their electrons with aligned spin(which generates a magnetic moment).Spin is...

The unit for the magnetic field is the a newton. b joule per coulomb. c volt. d tesla. 3. An electron (m = 9.11x10-31 kg, q = 1.60x10-19 C) is moving in a uniform magnetic field, perpendicular to...

A uniform magnetic field exerts a force on a moving charge which is equal to the...

A uniform magnetic field exerts a force on a moving charge which is equal to the charge times the vector product of the velocity and the magnetic field. Can this force change the magnitude of the velocity of the charge? Explain. Can both uniform electric and magnetic fields exist (for non-zero fields) where the net force on a charge is zero? If so, what are the constraints on the fields? If not, why not?

Problem 3 The purpose of this problem is to find the Net Magnetic Field force of the two electric currents at point P. There are two parallel wires carrying currents I1 = 15 A and I2 =25 A, as it is shown in the figure below. The arrow on each wire shows the direction of the current in the wire. The distance between the two wires is 10 Cm. The distance between point P and the wire (I1 ) on...
