A magnetic clamp ( 10 ) for use in clamping metal formwork in precast concrete manufacture includes a housing ( 12 ). A magnet ( 14 ) is displaceably arranged within the housing ( 12 ). A displacement mechanism ( 18 ) is displaceably arranged on the housing ( 12 ) to displace the magnet ( 14 ) relative to the housing ( 12 ). A force amplification mechanism ( 24 ) is connected to the magnet ( 14 ) and at least a portion of the force amplification mechanism ( 24 ) is interposed between the displacement mechanism ( 18 ) and the magnet ( 14 ).
