Acircular loop of wire with a radius of 15.0cm and oriented in the horizontal xy-plane is located in a region of uniform magnetic field. a field of 1.7t is directed along the positive z-direction, which is upward.

part a: if the loop is removed from the field region in a time interval of 2.4

ms , find the average emf that will be induced in the wire loop during the extraction process.

part b: if the coil is viewed looking down on it from above, is the induced current in the loop clockwise or counterclockwise?

could you explain this in a step by step process, and include reasoning to every assumption in relation to the right hand rule? .

See answer

Explanation:

The area of the circular loop is given by:

The magnetic flux is given by:

is parallel to and is constant in magnitude and direction therefore:

Part A)

initially the flux is

after the interval

the flux is

now, the EMF is defined as:

,

if we consider very small then we can re-write it as:

then:

Part B)

When looked down from above, the current flows counter clockwise, according to the right hand rule, if you place your thumb upwards (the direction of the magnetic field) and close your fingers, then the current will flow in the direction of your fingers.

dopamine..

"it was found that some people who were taking the drug l-dopa to raise their levels of dopamine were developing schizophrenic-like symptoms supporting research a strength of the dopamine hypothesis is that there are many studies which have shown support for the neurochemical explanation."

where is the circuit diagram ?
