Determine the force that is exerted on a car that has a net charge of 500 μC and moves at a speed of 80 m/s perpendicular to Earth’s magnetic field which is 5.0 x 10⁻⁵ T.
A wire carries a current of 5 A and is placed in a uniform magnetic field of 0.2 T perpendicular to the wire. What is the magnitude of the magnetic field created by the wire at a point 10 cm away from it?
Consider a wire carrying a current of 10 A. If the wire is bent into a circular loop with a radius of 0.1 m, what is the magnetic field at the center of the loop?
