Kieran measures the magnetic field of an electron beam. The beam strength is such that 1.70 x 1011 electrons pass a point every 1.30 us. What magnetic field does Kieran measure at a distance of1.60 cm from the beam center? :lT 10 A straight wire segment oflength 20.0 cm carries a current of 26.3 A and is immersed in a uniform external magnetic field. The magnetic force on the wire segment has magnitude 4.12 N. What is the minimum possible magnitude of the magnetic field
