Magnetic effect of current Worksheet-2  The magnetic field produced due to a circular wire at its centre is : A. in the plane of the wire B. perpendicular to the plane of the wire C. at 45° to the plane of the wire D. at 60° to the plane of the wire. The factors that affect the magnitude of the induced current are, 1. View Answer NCERT Question 15 (iii) - State the rule to determine the direction of a current induced in a coil due to its rotation in a magnetic field. CBSE Class 10 Science Board Exam 2020 Solution Set 1 by AGLASEM – Code 31/4/1. By taking two cunductiong coils and insert them over a non conducting cylindrical roll then on changing current flowing in one coil, an induced current is obtained in the other coil. where, I o = NBA ω = peak value of induced current, N = number of turns in the coil , finger points in the direction of magnetic field and direction of current respectively, then the thumb will be in the direction of motion or the force actingon the ... of the induced current changes once in each half revolution. State the rule to determine the direction of a (i) magnetic field produced around a straight conductor carrying current. 2. When you switch off coil A, the magnetic field stops quickly. Class-10 » Science. Coil C 1 is connected to a battery and key and C 2 with galvanometer G. No current is induced in a coil when the coil magnets both are stationary relative to one another. (b) and (c) are two other situations. This consists of 1 mark Questions, 3 Mark Numericals Questions, 5 Marks Numerical Questions and previous year questions from Magnetic Effects of Electric Current Chapter. At or near the top of their concerns is the common adverse effect (AE) of chemotherapy-induced nausea and vomiting (CINV). The maximum value of the induced emf is, E o = NABω . Stretch the thumb, forefinger and middle finger of right hand so that they are perpendicular to each other, as shown in Fig. If the rate of change of magnetic field is 10 T/s, find the magnitude and direction of the induced current if resistance of the loop is 25Ω. Name and state the rule to find the direction of: current induced in a coil due to its rotation in magnetic field. It has a gradient of 10 −3 T cm −1 along the negative x-direction (that is it increases by 10 − 3 T cm −1 as one moves in the negative x-direction), and it is decreasing in time at the rate of 10 −3 T s −1.
