State tight hand rule for magnetic field due to a current carrying wire

Answer 1

It's Fleming's Right hand rule in which we can find the magnetic field....Suppose you are point your first three fingers that is the thumb,index finger and the middle finger all in different directions making 90 degree angle(straight) then the thumb will be for force applied,index finger will be for magnetic field and the middle finger will represent the direction of current. The easy way to learn it is Take the thumb,index finger and middle finger as Father,Mother, and children then the First finger(thumb) will represent Force, 2nd finger(index finger) as Magnetic field, 3rd finger(middle finger) will represent the direction of current...
