The effect is called the Lenz Effect. The moving magnet causes small magnetic fields, called eddy currents, to form in the metal (brass, aluminum foil/tube ...). These eddy currents have their own magnetic field (all electrical currents do). This is what is interacting with the moving magnet.
1 Limited use: The Angel Card can only be used in Victoriaâs Secret and PINK stores. 2  While you may also use the card at Bath & Body Works stores, you will not earn Angel Reward points on those purchases.
I have used Disney Gift Cards at the park. First, make sure the card says Disney Gift Card, not Disney Store Gift Card (which is more limited to the store). You can use a Disney Gift Card within the parks. They cannot be used at restaurants within Downtown Disney. Exception should be that they should be accepted at Disney owned hotel restaurants. They are accepted as payment at the World of Disney Store and stores within the parks.
