Understanding Magnetic Field Interactions: How Do Perpendicular Fields Act?

[stuplato]

I have a few questions on magnetic fields:
.
1) If two magnetic fields are perpendicular, how do they act?
.
2) If the fields are setup as shown in the diagram [see attachment] how do they act?
.
For #2 I see how it is setup, but I get confused by all the circling ad everything
.
Is the strait wire (thick black one) pushed towards the right?
.
Thanks for the help!
.Note: in attachment the dot is out of page and x into

I can't see the attachment yet, but as to 1), the magnetic field is a vector. So if you have two of them, just add the two magnetic fields vectorally and you'll get a resultant magnetic field.
