Particle accelerators, such as the Large Hadron Collider, use magnetic fields to steer charged particles around a ring Consider a proton ring with 36 identical bending magnets connected by straight segments. The protons move along a 1.0-m-long circular arc as they pass through each magnet. Part A What magnetic field strength is needed in each magnet to steer protons around the ring with a speed of 2.0 x 10 m/s? Assume that the field is uniform inside the magnet, zero outside. Express your answer with the appropriate units
