A long straight wire carries an electric current of `2A`. The magnetic induction at a perpendicular distance of `5m` from the wire is `( mu_(0)4 pi xx 10^(7)Hm^(-1))`

A long straight alumnimium wire carries a current of 0.5 A. Computej the magnetic inductions at a distances 1 m from it.

A very long straight wire carries a current 5.2A. What is the magnitude of the magnetic field at a distance 3.1 cm from the wire?

A long straight wire carries a certain current and produces a magnetic field 2 xx 10^-4 Weber//m^2 at a perpendicular distance of 5 cm from the wire. An electron situated at 5 cm from the wire. An electron situated at 5cm from the wire moves with a velocity 10^7 m//s towards the wire along perpendicular to it. The force experience by the electron will be (charge on electron 1.6 xx 10^-19 C) .

A long straight wire is carrying a current of 12 A . The magnetic field at a distance of 8 cm is (mu_(0) =4pi xx 10^(-7) N A ^(2))
