A vertical wire carrying a current in the upward direction is placed in horizontal magnetic field directed towards north. The wire will experience a force directed towards

A vertical wire carrying a current in the upward direction is placed in horizontal magnetic field directed towards north. The wire will experience a force directed towards

A positively-charged particle (alpha particle) projected towards west is deflected towards north by a magnetic field. The direction of magnetic field is: (a) towards south (b) towards east (c) downward (d) upward

A long straight vertical conductor carries a current of 8A in the upward direction. What the magnitude of the resultant magnetic induction at a point in the horizonatal plane at a distance of 4 cm from the conductor towards South? (The horizontal compo-nent of earth's magnetic induction =4 xx 10^(-5)T )

A horizontal wire placed perpendicular to a magnetic field carries a current from left to right. The magnetic field is horizontal, directed towards you. What is the direction of magnetic force on the wire?

An electron is projectd horizontally with a kinetic energy of 10 keV. A magnetic feld of strength 1.0X10^(-7) T exists in the vertically upward direction. (a)will the electron deflect towards right or towards left of its motion? (b) calculate the sideways deflection of the electrion in travelling through 1m. make appropriate approximations.
