They'll still be magnets, but they'll never be able to touch each other where they were cut.
I hope this helps you! :-)
Answer:
b) the refracted ray has an angle of 90 degrees
Explanation:
The angle of incidence is measured with respect to the normal separation of the media. The critical angle for total internal reflection occurs is:

Here
and
are the refractive index of the mediums. This equation is an application of Snell's law, for the case where the refracted ray has an angle of
.
An object in motion stays in motion while an object at rest stays at rest.
