Draw on a piece of paper the uniform magnetic field directed out of a page, it means towards you. Magnetic field is uniform in space and decreasing in magnitude. Induced electric field as viewed from above is directed:

A. Counterclockwise
B Clockwise
C. Is zero because there is no conducting loop present
D. Electric field is always from positive charge to negative

Acyclotron is used to produce a beam of high-energy deuterons that then collide with a target to produce radioactive isotopes for a medical procedure. deuterons are nuclei of deuterium, an isotope of hydrogen, consisting of one neutron and one proton, with total mass 3.34×10−27kg. the deuterons exit the cyclotron with a kinetic energy of 6.40 mev .a-what is the speed of the deuterons when they exit? b-if the magnetic field inside the cyclotron is 1.25 t, what is the diameter of the deuterons' largest orbit, just before they exit? c-if the beam current is 350 μa how many deuterons strike the target each second?
