During a transcranial magnetic stimulation (tms) treatment, a magnetic field, typically of magnitude 5.00 t5.00 t , is produced in the brain using external coils. during the treatment, the current in the coils (and hence the magnetic field in the brain) rises from zero to its peak in about 80..0μs . assume that the magnetic field is uniform over a circular area of diameter 2.00×10−2 m2.00×10−2 m inside the brain. what is the magnitude of the average induced emf around this region of the brain during the treatment?

Explanation:

It is given that,

Initial magnetic field,

Final magnetic field,

Time,

Diameter of circular path,

Radius of circular path,

The induced emf around this region of the brain is given by :

So, the magnitude of the average induced emf around this region of the brain during the treatment is 19.63 volt. Hence, this is the required solution.

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
