Magnetic Force

A magnetic force arises when a charged particle or a current-carrying conductor is placed in a magnetic field. It is created because of the movement of the charged particles.

The Hall effect can be used to determine the density of mobile electrons in a conductor. A thin strip of the material being investigated is immersed in a magnetic field and oriented so that its surface is perpendicular to the field. In a particular measurement, the magnetic field strength was 0.735 T, the strip was 0.101 mm thick, the current along the strip was 2.95 A, and the Hall voltage between the strip's edges was 2.95 mV. Find the density n of mobile electrons in the material. The elementary charge is 1.602 x 10-19 C. 1.56 x104 n 3= -3 Incorrect
Three long parallel wires, lie perpendicular to this page, as shown in the figure, and carry the same current intensity I = 2 A. The current along the wire A is going into the page. The current along the wire B is also going into the page. The current along the wire C is coming out of the page. Knowing that d = 1 cm, find the direction and magnitude of the net force per unit length acting on the wire B. (Force per unit length just means divide the force by the length.) 2d d A В
