When you use the magnetic probe to measure a bar magnetic field, you first obtained a reading -0.006T, after you rotate the probe for 90 degres, you obtained another reading of -0.006T. What is the magnetic field magnitude at that point (in unit of T)? Question 3 2.5 pts When you use the magnetic probe to measure a bar magnetic field, you first obtained a reading 0.019T, after you rotate the the probe for a certain angle, you obtained a maximum reading of 0.029T. What is the angle (in degree) between the first and the maximum reading?
