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:
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 (19.1)
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 θ (18.1)
Like his British counterparts Sir Ronald Fisher and J. B. S. Haldane, Wright formulated a mathematical theory of evolution, thereby showing how frequencies of alleles and genotypes could change...
