Question

When is the magnetic flux maximum if the coil starts perpendicular to \[B\]?

विकल्प

• At \[t=0\]

• Only when \[\theta=90^\circ\]

• Only when \[\theta=270^\circ\]

• Whenever \[\sin(\omega t)=1\]

Answer 1

At \[t=0\], the coil is perpendicular to \[B\]. With this starting position, its magnetic flux is maximum.
