I think it is Q
Which of the following is correct for the representation of the magnetic field shown below? Magnetic field is in the plane of paper. Magnetic field is pointing upward from the plane of paper. Magnetic field is downward through the plane of paper. Magnetic field is downward in the plane of paper.
i forget a bunch of E&M class.
It should be stronger closer to the centre
I don't know how to describe, suppose the paper are on the table, the current is going from the above of the table to the table, so that our thumb is point directly to the table, other 4 finger will go clockwise.
im talking about the second question
Magnetic field is downward through the plane of paper. my original answer was this one
X does represent it's going through the paper
a dot would mean it's coming out
point the thumb toward the current, the direction of the rest of our fingers is the direction of the magnetic field.
Thanks for making the question. My knowledge is almost gone.
