What is the magnitude of magnetic moment of the magnet? | A closely wound solenoid of 800 turns and area of cross section 2.5 × 10–4 m2 carries a current of 3.0 A. Explain the sense in which the solenoid acts like a bar magnet. What is its associated magnetic moment? | If the solenoid in Exercise 5.5 is free to turn about the vertical direction and a uniform horizontal magnetic field of 0.25 T is applied, what is the magnitude of torque on the solenoid when its axis makes an angle of 30° with the direction of applied field? | A short bar magnet has a magnetic moment of 0.48 J T –1. Give the direction and magnitude of the magnetic field produced by the magnet at a distance of 10 cm from the centre of the magnet on (a) the axis, (b) the equatorial lines (normal bisector) of the magnet | NCERT Solutions | NEET Toppers | Magnetism & Matter in 1 Shot: FULL CHAPTER COVERAGE (Theory) LearnoHub.com (formerly called ExamFear Education) is a Free Education platform with more than 6000 videos on Physics, Chemistry, Maths, Biology, English, Science experiments, tips & tricks and motivational videos for Classes 6 to 12.
