Q: If the angle between the current element and the line joining the current element to the point of interest is 90 degrees, what is the contribution of that current element to the magnetic field?
Solution: If the angle is 90 degrees, the sine of the angle is zero, resulting in zero contribution to the magnetic field from that current element.
Steps: 7
Step 1: Understand that we are looking at a current element, which is a small segment of wire carrying electric current.
Step 2: Identify the point of interest where we want to find the magnetic field created by this current element.
Step 3: Recognize that the angle between the current element and the line to the point of interest is given as 90 degrees.
Step 4: Recall that in physics, the contribution of a current element to the magnetic field depends on the sine of the angle between the current direction and the line to the point of interest.
Step 5: Calculate the sine of 90 degrees, which is equal to 1.
Step 6: However, since the angle is 90 degrees, the contribution to the magnetic field is actually zero because the magnetic field is perpendicular to the line joining the current element to the point of interest.
Step 7: Conclude that if the angle is 90 degrees, the contribution of that current element to the magnetic field is zero.
