The invention provides a magnetic trolling reel and belongs to the technical field of textile machinery. The magnetic trolling reel comprises a power shaft and a trolling felloe which can be matched with the power shaft in a rotation mode. The power shaft passes through the middle of the trolling felloe. An inner magnetic stripe is arranged on the outer surface of the power shaft. The inner surface of the trolling felloe is provided with an outer magnetic stripe which exists in pairs with the inner magnetic stripe. The magnetic poles of the corresponding surfaces of the inner magnetic stripe and the outer magnetic stripe are opposite. The magnetic trolling reel is arranged on a reeling machine, when thread jamming of the reeling machine occurs, the force applied on the trolling felloe by the reeled threads is greater than the magnetic force between the inner magnetic stripe and the outer magnetic stripe. The power shaft idles opposite to the trolling felloe, the reeled threads can not be snapped and alarm is sent out to remind people for attention.
