MacBook Air Charger issues

My charger for my MacBook Air is seeming to have problems. It uses a magnet when charging however one day the charger seemed bent a bit and now when i charge it, it has issues as it is difficult to charge. Sometimes i am able to charge it, but it takes a long time as I have to wiggle it around until the charger works. I was just wondering if this issue is repairable if i were to bring it into the Apple store.
