EXPERIMENT 12 Current Balance Introduction The current balance is used to measure the force of repulsion between identical, oppositely di-rected, currents in parallel conductors. In this experiment you will: 1) Determine how the magnetic force of one current-carrying conductor on a parallel current-
In this experiment you will use a current balance in which the upper conductor is free to pivot on knife edges. The upper conductor is balanced so that the wires are a small distance apart.
The objective of this experiment is to measure the ef-fects of a magnetic field on a current carrying conduc-tor. Theory. A magnetic field exerts a force, ~FB, on a moving charge. The magnitude of ~FB is: FB = qvB sin (19.1)
The objective of this lab is to measure the effects of a magnetic field on a current carrying conductor by selectively varying a number of parameters. Theory: A magnetic field exerts a force F on a. B. moving positive charge that is given by the vector cross product. Current Limiting Resistor.
Experiment 18: The Current Balance. Advance Reading. Text: Magnetic force, magnetic field. Objective. The objective of this experiment is to measure the ef-fects of a magnetic field on a current carrying conduc-tor. Theory. A magnetic field exerts a force, FB, on a moving charge. The magnitude of FB is: FB = qvB sin θ (18.1)
Current Balance. Theory: A current-carrying wire in a magnetic field experiences a force that is usually referred to as a magnetic force. The magnitude and direction of this force depend on four variables: the magnitude of the current (I); the length of the wire (L); the strength of the magnetic field (B); and the angle between the field and ...
The current to be measured in this experiment is passed in opposite directions through two parallel horizontal bars that are connected in series. The lower bar is fixed and the upper bar is balanced a few millimeters above it on a pair of knife-edges. The upper bar has.
