What is a transverse magnetic field and how does it affect alpha particles?

[lingling]

What is the meaning of a ' transverse magnetic field '?

I 've seen it once in a question.
It asked 'when a beam of alpha particles enter a transverse magnetic field, ...'

I guessed it means the direction of the beam traveling is perpendicular to the direction of magnetic field. Is this right?

Correct

Yes, for example, if the beam is in the xOy plane, the (probably homogenous) magnetic field (induction vector $\vec{B}$) is along the Oz axis.
