UESTIONS 1 A beam of 20Mev protons emerges from a cyclotron

UESTIONS 1. A beam of 20-Mev protons emerges from a cyclotron. Do Consider a magnetic field line. Is the magnitude of B constant or variable along such a line? Can you give an example of these particles cause a magnetic field? 2. Discuss analogies and differences between Coulomb\'s law each case? 4. In electronics, wires that carry equal but opposite cuments ae and the Biot-Savart law.

Solution

1. Yes ,magnetic field is produced from moving charge. because the particles emerges from cycltron are charged particles.
