Answer:
3. Large butterfly in flight, flying through the air?
Explanation:
Momentum is simply defined as the quantity of motion a body possess. It is mathematically given as;
Momentum = mass x velocity
The larger the mass, the larger the momentum and also the velocity
Since the large butterfly is in flight, it has the largest velocity.
A sleeping bear and resting caterpillar have no momentum because their velocity is 0
A magnetic field is actually generated by a moving current (or moving electric charge specifically). The magnetic field generated by a moving current can be found by using the right hand rule, point your right thumb in the direction of current flow, then the wrap of your fingers will tell you what direction the magnetic field is. In the case of current traveling up a wire, the magnetic field generated will encircle the wire. Similarly electromagnets work by having a wire coil, and causing current to spin in a circle, generating a magnetic field perpendicular to the current flow (again right hand rule).
So if you were to take a permenant magnet and cut a hole in it then string a straight wire through it... my guess is nothing too interesting would happen. The two different magnetic fields might ineteract in a peculiar way, but nothing too fascinating, perhaps if you give me more context as to what you might think would happen or what made you come up with this question I could help.
