The relation between `mu` and `H` for a specimen of iron is `mu=[(0.4)/(H)+12xx10^(-4)]henry//metre`.
The value of `H` which produces flux density of `1` tesla will be

In the graph given below. If the slop is 4.12 xx 10^(-15) V-sec , then value of 'h' should be

The wing span of an aeroplane is 20 metre. It is flying in a field, where the verticle component of magnetic field of earth is 5xx10^(-5) tesla, with velocity 360 km//h . The potential difference produced between the blades will be

An electron revolves in a circle of radius 0.4 A^(0) ith a speed of 10^6 ms^(-1) in a hydrogen atom. The magnetic field produced at the centre of the orbit due to motion of the electron, in tesla, is [mu_(0)=4pixx10^(-7)H//m]
