Direction of Magnetic Field in a Toroid with Clockwise Current Loop?

Inside the toroid, in which direction does the magnetic field point, if the current is going clockwise around the loop?

So I tried to consider the fields due to two points on opposite sides of the toroid. Then I got stuck because I don't know what direction their fields added up. What do I do?
 
Physics news on Phys.org
Use a right hand rule to determine the direction of the field.
 
I did, I got counterclockwise but that wasn't the answer.

Counterclockwise isn't correct.

Imagine the loop on the surface of a table (the x-y plane). If the current is going clockwise, use the right hand rule in either of two ways:
(1) use it to find the field around any segment of current (that will tell you the field direction in the center of the loop)
(2) apply it direction to the current loop

The answer must be out of the table or into the table.

Method one is described here: http://hyperphysics.phy-astr.gsu.edu/hbase/magnetic/magcur.html#c1"

oh... I think I into the table. The current is clockwise, so my fingers curl into the table. Is that right?
