A1 meter long straight wire is situated along the x-axis with one end at the origin and the other at (1m,0,0). the wire carries a current of 10 a in the +x direction. use the biot-savart law and calculate the magnetic field due to the current in the wire at the point (0.5m, 0.5m, 0).

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?
