Can a watch-sized electromagnet deflect a bullet? Explain your answer.

An unknown particle travelling with a velocity of 3.12 x 105 m/s enters a 54 mT magnetic field and curves in a circular path with a radius of 12 cm. Determine the charge-to-mass ratio, enter that value in the first blank (with three significant figures of accuracy). From the table of particles on your data sheet (showing data for the charge and mass for alpha particle, electron, proton, and neutron), the identity of the unknown particle is most likely.

A cyclotron (figure) designed to accelerate protons has an outer radius of 0.333 m. The protons are emitted nearly at rest from a source at the center and are accelerated through 572 V each time they cross the gap between the dees. The dees are between the poles of an electromagnet where the field is 0.720 T. The black, dashed, curved lines Alternating AV represent the path of the particles. -Dg After being accelerated, the particles exit here. -North pole of magnet (a) Find the cyclotron frequency for the protons in this cyclotron. 1.04e33 x rad/s (b) Find the speed at which protons exit the cyclotron. m/s (c) Find their maximum kinetic energy. ev (d) How many revolutions does a proton make in the cyclotron? revolutions (e) For what time interval does the proton accelerate? awranca Barke kay Nationallab

Let's take the Earth's magnetic field BE = 1.70 x 10-4 T pointing north. A metal cable attached to a space station stretches by 1.4 km. What would be the potential difference ( ΔΔ V) that develops between the ends of the cable if it’s traveling eastbound around Earth with a speed 4.4 km/s?
