A proton moves in a circular path and is perpendicular to a magnetic field of magnitude 2 T. The radius of the path is 10 mm. Calculate the proton energy in eV

Consider a straight conductor of length 15 cm. The conductor moves at right angles to a magnetic field of uniform strength B = 10-³ T generating e.m.f. of 2,5 x 10-5 V. Calculate the velocity of the straight conductor. Give your answer in Sl units. Answer: m/s ♦

A particle passes through a mass spectrometer as illustrated in the figure below. The electric field between the plates of the velocity selector has a magnitude of 8060 V/m, and the magnetic fields in both the velocity selector and the deflection chamber have magnitudes of 0.0920 T. In the deflection chamber the particle strikes a photographic plate 39.6 cm removed from its exit point after traveling in a semicircle. The diagram depicts a velocity selector. The plane of the page is filled with symmetrically arranged crosses labeled vector B0, in above a horizontal plate, and vector Bin below the horizontal plate. Below the horizontal plate, two vertical plates are placed parallel to each other in the right position of the field. The left plate is positively charged and the right plate is negatively charged. The electric field vector E points from the positive plate to the right toward the negative plate. A positively charged particle of charge q and velocity vector v pointing upward…

The ions were accelerated by an applied voltage right before entering the magnetic field.What was the applied voltage if the ions accelerated from rest? V = ?

A proton travels clockwise in the plane of the page under the influence of a magnetic field of 3T a) If the particle has an energy of 10-15J, find the radius of the circle b) What is the direction of the field? c)  A long wire carries a current of 10A. A closed loop, in the form of a rectangle with the dimensions in the figure carries a current of 4 A. The side of the loop nearest the wire is 1mm from the wire. Find the force on the loop.
