Brief Answer: Please find detailed answer below Detailed Answer: Hi, Thanks for writing in to us. I have read through your query in detail. A magnetic band worn in the wrist will not cause any significant observable effects in most people. The strength of the magnet is very low. However in persons with a cardiac pace maker or any such electronic equipment implanted within themselves, a rare possibility of malfunctioning of such devices exists. This can be exlplained by electromagnetic interferences due to external magnetic fields. Hope your query is answered. Do write back if you have any doubts. Regards, Dr.Vivek
