In a TV tube, the electrons are accelerated from the rear to the front. What is the direction of the current?

A current carrying wire is placed along east and west in a magnetic field directed north wards. If the current in the wire is directed east wards, the direction of force on the wire is

Asseration: Induced potential across a coil and therefore induced current is always opposite to the direction of current due to external source. Reason: Lenz's law states that it always opposes the cause due to which it is being produced.
