Researching further, the friends find that soft iron is readily magnetized when it is placed in the magnetic field of an inductor, such as the coils in this simulation. When the domains of the iron are aligned in the inductor's field, they can increase the strength of the magnetic field significantly. Baraz asks Eli how the magnetic ring in this simulation affects the induced emf. What should be his response?

f is prop to m1xm2 double m1 double force

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.

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.
