The magnetic field due to a bar magnet is non-uniform. Give tests to analyze your progress and evaluate where you stand in terms of your JEE preparation. As i. e., then the is taken as unity, so the equation is. Two plates (as in Fig. Trending Categories. The figure shows a circular region of radius R in which uniform magnetic field is increasing at a constant rate dB/dt =. The Question and answers have been prepared. Current Electricity.
Figure shows a circular area of radius R where a uniform magnetic fiel... Opt d. Question Description. The self-inductance of the coil is. From the given, localid="1663150045833". If the magnetic induction varies in magnitude and direction at different points in a region, the magnetic field is said to be non-uniform.
Ask your doubts live everyday Join our live doubt clearing session conducted by our experts. Proper planning to complete syllabus is the key to get a decent rank in JEE. Therefore, the magnitude of an induced magnetic field at a radial distance is. A) Perpendicular to magnetic field lines, in a direction defined by the right-hand rule. The average mass of rain drops is kg and their average terminal velocity is Calculate the energy transferred by rain to each square metre of the surface at a place which receives of rain in a year. A body of mass under the action of constant force has velocity at as m/s and at as m/s. When it delivers 30A the potential is 120V.
The magnetic field is increasing at a rate d B d t. The induced electric field at a distance r from the centre for r < R is. 70 mWb is directed outward. E Denotes electric field. Defined & explained in the simplest way possible. Reason: Work done in a closed path in the induced electric field is non-zero. The primary and secondary coils of a transformer have and turns, respectively. Both assertion and reason are false statements. From the formula, for magnetic field inside the circle, i. e., as.
How far above the centre of the target the rifle must be aimed in order to hit the target? The initial speed of a bullet fired from a rifle is. If the velocity of conductor becomes double, the induced current will be. Assertion is a true statement but the reason is false. National Mock Tests. Covers all topics & solutions for JEE 2023 Exam. The force is: Laws of Motion. Effective Resume Writing. Test Series/Daily assignments. Non-uniform along its length.
Physics Tutorial on Magnetic Fields. HR Interview Questions. Reason: It is on account of self-inductance that the coil opposes any change in current passing through it. If the magnetic flux linked with the primary coil is given by where is in weber, is time in second and is a constant, then the output voltage across the secondary coil is: Questions from JEE Main 2014. By using the concept of magnetic field for the non-uniform electric field, the magnetic field inside and outside the circle can be found. And access revision papers with marking schemes, video lessons and live classes. The width of the pavement is x meters as shown. Cannot be predicted. The electric field produced is. B) What is the current in the wires attached to the plates? Can you explain this answer?. The formula is as follows: Where, is the magnetic field, is the flux. Get premium membership.
Practice over 30000+ questions starting from basic level to JEE advance level. The potential across a generator is 125V when it is delivering 10A. The induced current is zero at: 1. t = 0.
