A thin infinitely large sheet lying in yz plane carries a current of linear current density `lambda`. The current is in negative y direction and `lambda` represents current per unit length measured along z-axis. Find the magnetic field near the sheet : (Magnetic field due to the sheet will be parallel to sheet)

(Long sheet with `lambda = ("current")/("length")`)

Find the Electric field due to two infinite plane parallel sheet of charge.

A large metal sheet carries an electric current along its surface. Current per unit length is lambda . Magnetic field near the metal sheet is.

A large metal sheet carries an electric current along its surface. Current per unit length is lambda . Magnetic field near the metal sheet is.

A direct current l flow along the length of an infinitely long striaght thin walled pipe then the magnetic field is

A direct current I Flows along the length of an infinitely long straight thin walled pipe then the magnetic field is

A long solenoid carrying a current produces a magnetic field B along its axis. IF the current is doubled and the number of turns per unit length is halved, the new value of he magnetic field is-

Long, straight conductors with square cross sections and each carrying current I are laid side-by-side to form an infinite current sheet as shown in Fig. The conductor lies in the x-y plane, are parallel to the y-axis and carry current in the +y direction. There are n conductors per unit length measured along x-axis. what are the magnitude and direction of the magnetic field for distance a below the current sheet?
