Three long current-carrying wires intersect forming an equilateral triangle of side l. The relative magnitude and direction of the current on each wire are shown in the image below. 31 21 What is the magnetic field at a point P at the center of the triangle? (D represents the shortest distance from each wire to point P.) O poI/2nD, into the screen. HoI/2ñD,out of the screen. O 2µoI/TD, into the screen. 2µoI/TD, out of the screen. None of the other answers.

An electron is introduced into a uniform magnetic field, Bx = 50.0 μTesla directed at right angles to the electron’s velocity vy = 5 x105 m/s. The electron subsequently moves in a circular path. What is the radius of the circular path? Select one: a. 2.84 cm b. 5.68 cm c. 56.8 cm d. 2.84 m

4G OA 1:0Y A long straight wire is bent as shown to form two parallel straight wires and a semicircle (radius = 2.0 m). A current of 24 A is directed as shown. What is the magnitude of the magnetic field ( in units of uT) at point C, the center of the circle along which the semicircle lies? c'

Determine what the magnetic field is at point A, point B and point C.

Please answer it within 30 minutes.I will upvote! Problem: What is the radius of the path of an electron that travels through a .76 T uniform magnetic field at a speed of 70,000 m.
