The magnetic field at O is The magnetic field at O is November 18, 2021 Category: Cengage NEET by C.P Singh , Chapter 5 - Magnetic Field , Part 2 , Facebook Messenger WhatsApp Share this:TwitterFacebook Related A 250- Turn rectangular coil of length 2.1 cm and width 1.25 cm carries a current of 85 μA and subjected to a magnetic field of strength 0.85 T. Work done for rotating the coil by 1800 against the torque isA particle with charge q having momentum p enters a uniform magnetic field normally. The magnetic filed has magnitude B and is confined to a region of width d, where d< Bq/ p . The particle is deflected by an angle θ in crossing the field.A proton and an alpha particle are projected in a magnetic field which exists in the width of region d. Compare the angles of deviation suffered by the proton and the alpha particle if before entering the magnetic field both the particles. a. have the same momentum, b. have the same kinetic energy, and c. are accelerated through the same potential difference. Take mα = 4 mp,qα = 2 qp.
