An ion, stripped of a single electron, enters the magnetic field B of a mass spectrometer with a velocity v as shown. It hits the detector a distance 2r from place where it enters the B-field. The direction of the B-field is into the page. Which is/are all the change(s) that INCREASE the distance travelled by the ion from the place where it enters the B-field to where it hits the detector?

In the PHY104 lab, you are looking at a coil made from copper which lies flat on a table. A magnetic field of 0.01 T created by a permanent magnet points straight up and is passing through the copper coil. Suddenly you notice that the magnetic field vanishes. According to the Lenz’s law what is the direction of the induced current in the coil while the magnetic field vanishes, when you look at it from above?
