From $$n=12$$$$π$$MBI     As nαB       	$$n1n2=$$Β$$1B2$$      $$B1=BH=12$$  μT      $$B2=$$      resultant of  B and BH      , Where $$B=$$μ$$0i2$$π d     	$$B=2$$×$$10$$−$$7$$×$$1520$$×$$10$$−$$2$$     	$$B=15$$  μT     $$B2=15$$−$$12=3$$  μT      ∴  $$10n2=123$$  ⇒  $$n2=5$$  Hz

A short magnet oscillates in vibration magneto mater with a frequency $10 H z$ where horizontal component of earth’s magnetic field is 12 $μ T .$ A downward current of 15 A is established in the vertical wire of infinite length placed 20 cm west of the magnet. Then the new frequency is
