Trackpad become erratic and jump when adapter is plugged in
I have recently bought a new authentic Apple 60W MagSafe Power Adaptor, but when I start charging using this adapter, my trackpad becomes unresponsive, and the cursor jumps around the screen when in contact with fingers. If I try to move the cursor, it jumps around and moves where I don't want it to go. The issue disappears when I remove my adapter. However, whenever I charge, the issue resurfaces.
The adapter is not a third party charger, and is brand new.

Running OS X 10.10.2 (Yosemite) on a Mid 2012 13 inch MacBook Pro with 2.5Ghz Intel Core i5, 4GB 1600 MHz DDR3 Memory
Any help on this issue would be very much appreciated 😀
