**max. length by which the bar magnet can be shortened or machined without being damaged.

Note: Direct mounting of the bar magnet in iron reduced the holding power by up to 15% due to magnetic short circuiting. To avoid this, certain distances need to be maintained between the brass casing of the bar magnet and the iron. The distances are also to be adhered to if the bar magnet was shortened by dimension h. Please refer the recommended distances:
