![]() Visitors can click on a particular category to see all posts related to that category. In which direction is the force due to the magnetic field experienced by the wire?Īll categories of this website are listed below with number of posts in each category for better navigation. A wire whose direction of current flow is as shown in the figure is placed there. (v) The direction of magnetic field at a place is coming out of the paper. ![]() (d) It converts electric energy into magnetic energy (c) It converts magnetic energy into electric energy (b) It converts mechanical energy into electrical energy (a) It converts electrical energy into mechanical energy (iv) Which one of the following is true about electric motor? (d) a soft iron core on which the coil is wound (c) a permanent magnet to rotate the armature (b) effectively large number of turns of conducing wire in the current carrying coil (a) an electromagnet to rotate the armature. ![]() (iii) Commercial electric motors do not use The coil continues its rotation in magnetic field even if there is no current in circuit. The direction of force, acting on the coil is given by Fleming’s left hand rule. The speed of rotation of the motor is increased, if the value of current is increased. As the current reverses in the coil for every half turn, the coil rotates in one direction. (ii) The student is still testing on the feasibility of using metal strips in the model. (d) First half anti-clockwise and other half clockwise (c) First half clockwise and other half anti-clockwise (i) The direction of rotation of the coil, when viewed from the front by the student is The metal strips are connected to the power supply with a rheostat. To verify that the behavior is accurately described by Faraday's law.He fixed the two ends of the coil to a pair of curved elastic metal strips. To observe how a moving magnet can be used to generate electric current. To verify that this behavior is accurately described by Fleming’s Left Hand Rule. Here we are modelling the behavior and properties of the magnetic field when the conductor takes the shape of a loopįorce on a current carrying conductor in a magnetic field ![]() This experiment is a special case of the fundamental fact that a current carrying conductor has a magnetic field around it. The magnetic field lines around current carrying solenoid. This is an activity to observe the magnetic effects of current. Magnetic field lines around current carrying conductor To study the dependence of potential difference (V) across a resistor on the current (I) passing through it and to determine its resistance. Here are the top 10 innovative physics science projects for inter-school, and. This is done by observing the arrangement of Iron Filing and behavior of magnetic compass around the Magnet. Top 10 Innovative Physics Projects for Science Exhibition class 10 to 12: Making of physics working model and projects for science fair or science exhibition, Physics category has too many options to make interesting award-winning projects than biology and chemistry. This experiment is to study the magnetic field produced by a bar magnet. To study the field lines formed around a bar magnet Hooke's law of elasticity is an approximation that states that the extension of a spring is in direct proportion with the load applied to it. ![]() To determine the focal length of Concave mirror by obtaining the image of a distant object To study reflection in concave mirror and observe image formation in different positions of the object Measure the angle of incidence, angle of refraction, angle of emergence and interpret the result. To trace the path of a ray of light passing through a rectangular glass slab for different angles of incidence. To study refraction of light in rectangular glass slab ![]()
