A buckle is respectively provided on frame above and below shaft, is buckled for being clamped rocker arm, when rocker arm is stuck, palm will be in water
Level state;The rear and front end of palm is equipped with sliding slot, is equipped with conductor between two sliding slots, conductor can move left and right along the chute;The left hand palm
It is equipped in the heart from lower right to upper left oblique slot, is provided with long hole on conductor, the junction of oblique slot and long hole is inserted with outer
Electric current arrow is connect, external impressed current arrow is equipped with pushing handle, is equipped with stress arrow on the left of conductor, pushes up external impressed current by pushing handle
Arrow, conductor will be moved along the direction of stress arrow meaning;The right hand centre of the palm is equipped with oblique slot from lower left to upper right side, on conductor
It is provided with long hole, the junction of oblique slot and long hole is inserted with induced current arrow, and movement arrow is equipped on the right side of conductor, and movement arrow is equipped with
Pushing handle pushes to the right conductor by pushing handle, and direction of the induced current arrow then along arrow meaning moves.
Returning pull-spring is equipped between on the right side of conductor on the left hand centre of the palm and on the right side of the centre of the palm;Conductor on the right hand centre of the palm is left
Returning pull-spring is equipped between on the left of side and the centre of the palm.
The magnetic line of force is labeled on the left hand centre of the palm and the right hand centre of the palm.
Purpose of the present invention good effect is as follows: the present invention is used to demonstrate at any time, can be significantly by operating repeatedly
The difficulty for solidifying one's knowledge acquired, and avoiding the need for place, needing equipment, need to install, need the time greatly mitigates
The burden of student.The present invention can both demonstrate left hand rule, can also demonstrate the right-hand rule, and a tractor serves several purposes is very convenient.
