Do bar magnets and straight coils of wire have uniform magnetic fields

I just need to know if I'm right. The question was "mention 2 different arrangements where there is a uniform magnetic field."

If I'm not right, could you explain? Thank you!

Bar magnets do not have a uniform (constant) magnetic field , because the field gets weaker as you get further from the poles or sides.

You might just get away with 'between the N and S pole of a pair of facing magnets, like this;
[N--S] [S..N], though it's not very uniform..

A straight coil might be acceptable - providing you note it is the INSIDE that has the uniform magnetic field, not the outside (the field on the outside is like a bar magnet's).

I expect the answers required were:
- the inside of a long thin solenoid;
- between a pair of thin coils separated by a distance equal to their radius (these are usually called Helmholtz coils - see link).
