Introduction: As we learned in lecture, a magnetic field is produced whenever a current flows. The magnetic field lines will form circular loops around a long straight wire carrying current. Current Balance laboratory pg 2 The direction of the field is assigned by the right and rule which is applied as follows: 1) Pint the thumb of your right hand in the direction of the conventional current. 2) Imagine curling the fingers of your right hand around the wire. 3) The fingers of your right hand now point in the direction of the magnetic field loops.
Current Balance laboratory pg 3 Not only does current produce a magnetic field, but a current placed in an external magnetic field will experience a force. The magnetic force on a current carrying wire is: F = IL x B Eq (1) where B is the magnetic field in Tesla, I is the current in amperes. The magnitude of L is the length of the wire in meters and the vector L is in the direction of the current I .
