1.	A wire placed along north-south direction carries a current of `5A` from south to north. Find the magnetic field due to a `1cm` piece of wire at a point `200cm` north east from the piece.
Answer» Correct Answer - `88xx10^(-10)T`, acting vertically downwards `dB=(mu_0)/(4pi)(Idlsintheta)/(r^2)=(10^-7xx5xx10^-2xxsin45^@)/((2)^2)` `=88xx10^(-10)T` Its direction is vertically downwards.
