    JEE Main & Advanced 2019
    JEE Main & Advanced 2019

    There are two phases in Joint Entrance Examination (JEE) i.e., JEE Main and JEE Advanced. JEE Main is conducted by Central Board of Secondary Education (CBSE) while JEE Advanced is conducted by one of the IITs. The students who secure rank among top 224000 students will be eligible to appear for JEE Advanced 2019. Students who qualify both exams will be short-listed for the admission to engineering courses at IITs, NITs, and CFTIs.

    Most of the aspirants preparing for JEE Main and JEE Advanced are fresh candidates which means they are going to appear in the exam right after their board exams.

    The other category is of repeaters who are going to take the JEE Main test for the second time to improve their rank. Such candidates would have been preparing for this entrance exam by taking various coaching classes or simply doing self-studies.

    Let us discuss first about the JEE Main, the preliminary test. The syllabus of the JEE Main exam is based on the class 11th and class 12th NCERT books which is a favorable factor for the fresher students. But repeaters can also take a lead by revising their whole year’s learning in a proper way.

    All the aspirants need to keep a track of their preparedness by practicing more and more questions based on each important topic for JEE Main test.

    In this article, we will provide you the 5 most important questions from different topics of all subjects i.e., Physics, Chemistry and Mathematics on daily basis.

    Find the important questions from the topic Relations and Functions . Students always get 1-2 questions from this topic in the examination.

    Every day you will get the entirely FRESH 5 Questions for JEE Main.

    3rd April, 2018: 5 Important Questions of Electromagnetic Induction for JEE Main 2019.

    Q 1. An aluminium ring B faces an electromagnet A. The current / through A can be altered,

    JEE Electromagnetic Induction

    Options:

    (a) If i increase, A will repel B

    (b) If i increase, A will attract B

    (c) If i increase, A will repel B

    (d) Whether i increase or decrease, B will not experience any force

    Ans. Option (a) is correct

    Explanation:

    If current is passed through solenoid A as shown. Current entering at end A is clockwise. When seen from the side of A, so it develops south polarity at A and north polarity at B. When current / through A increase, it is like north of the magnet approaching the ring B and due to Lenz's law face of ring B facing B develops north polarity and hence there is repulsion between the two.

    Q 2. The current in the winding on a torpid is 4.0 A. There are 200 turns and the mean circumferential length is 20 cm. If the inside magnetic field is 2.0 T, the relative permeability is near to

    Options:

    (a) 1000                   

    (b) 2500                   

    (c) 2000                   

    (d) 4000

    Ans. Option (b) is correct

    JEE Electromagnetic Induction

    Q 3. A metallic rod of length ‘l’is tied to a string of length ‘2l’ and made to rotate with angular speed on a horizontal table with one of the string fixed. If there is a vertical magnetic field B in the region, the emf induced across the ends of the rod is

    JEE Electromagnetic Induction

    Ans. Option (d) is correct

    JEE Electromagnetic Induction

    Q 4. A circular loop of radius 0.4 cm lies parallel to a much bigger circular loop of radius 40 cm. The centre of the smaller loop is on the axis of the bigger loop. The distance between their centres is 25 cm. If a current of 4.0 A flows through the bigger loop, then the flux linked with smaller loop is

    JEE Electromagnetic Induction

    JEE Electromagnetic Induction

    Q 5. A current carrying infinitely long wire is kept along the diameter of a circular wire loop, without touching it. The correct statement (s) is / (are)

    Options:

    (a) The emf induced in the loop is zero if the current is constant

    (b) The emf induced in the loop is finite if the current is constant

    (c) The emf induced in the loop is zero if the current decreases at a steady rate

    (d) The emf induced in the loop is finite if the current decreases at a steady rate

    Ans. Option (d) is correct

    Explanation:

    JEE Electromagnetic Induction

    Due to current in the straight wire, net magnetic flux from the circular loop is zero. This is because; magnetic field is inward in half of the circle and outward in the other half of the circle. Therefore, change in current will not cause any change in magnetic flux from the loop. Therefore, induced emf under all condition through the circular loop is zero.
