The normal to this coil is parallel to a uniform and constant (in time) magnetic field of 1.80 T. An emf that has a magnitude of 2.40 V is induced in this coil because the coil's area A is shrinking. What is the magnitude of AA/At, which is the rate (in m²/s) at which the area changes? Number i UnitsPr1. The figure shows the cross-section of a long, straight, cylindrical coil (solenoid) of radius r = 10 cm. The number of turns per unit length is n = 500 m-1. A direct current I = 1,0 A flows clockwise in the solenoid. A charged particle accelerated by a voltage 1000 V enters into the solenoid through a gap between the coils at point A. The velocity of the particle at point A is pointing along the radius. The particle is traveling inside the solenoid in a plane perpendicular to its axis and exits at point C at an angle a = 60° to its initial direction. 60 Av a) Determine the sign of the charge of the particle. b) What is the radius of the particle's trajectory? c) Find the charge-to-mass (Q/m) ratio of the particle.
