Abstract
The utility model discloses an experimental device for a conductor to cut a magnetic induction line to generate an induction current. The device comprises a guide rail, a magnet, a wire stick, a micro-current sensor, a collector, and a computer, wherein, the guide rail is attracted by the magnet, the wire stick is laid on the guide rail, and the guide rail, the current sensor, the collector, and the computer are connected through a conducting wire. The utility model has the advantages that the structure is simple and economical, the effect is obvious and stable, the assembly is more convenient than the same device, and the device is suitable for student grouping experiments.
Description
Technical field:
The present invention relates to a kind of experimental provision, relate in particular to the experimental provision of the generating induced current by conductor cutting magnetic induction line that a kind of senior middle school physics teaching uses.
Background technology:
In senior middle school physics teaching " closed-loop path segment conductor cutting magnetic induction line produce induction current " be the focal points content be again the teaching difficulty content, and the best method that breaks through this difficult point be each student can both be done it yourself one do " closed-loop path segment conductor cutting magnetic induction line produce induction current " grouping experiment.But, the present domestic way in 3 that roughly has.
1, allows the part lead in the closed-loop path on the guide rail that the tinsel that is in horsehoe magnet is made, move, observe the induction current of generation by the reometer of repacking.Shortcoming is: the reometer that needs repacking reometer or purchase special producing; Because track contacts bad with lead and magnetic field is strong inadequately, the effect instability.
2, allow the part lead in the closed-loop path move on the guide rail that the tinsel that is in horsehoe magnet is made, gather by DIS current acquisition device, the induction current of generation is removed to observe in the reometer interface from computer screen then.Its effect religion way 1 increases, but still stable inadequately, effect is not fairly obvious.
3, allow the part of multiturn coil replace the motion of wire rod.Though this way effect obviously, stable, when lead of explanation was done the cutting magnetic induction line motion and produced this problem of induction current, the student usually produced the sensation of not admitting, and accepts difficulty.
Based on above 3 points, existing grouping experiment device need improve.
Summary of the invention:
Deficiency at prior art exists the object of the present invention is to provide a kind of closed-loop path segment conductor simple and easy, that cost is low, effect is obvious and stable to do cutting magnetic induction line and produces faradic experimental provision.
Goal of the invention of the present invention is achieved through the following technical solutions:
The principle that the present invention makees the experimental provision of generating induced current by conductor cutting magnetic induction line is: when the closed-loop path segment conductor is done the cutting magnetic induction line motion on smooth guide rail, will produce induction current in the loop.
A kind of experimental provision of generating induced current by conductor cutting magnetic induction line comprises low current sensor, collector, computer that guide rail, magnet, wire rod, DIS use.Described guide rail is held by magnet, and wire rod lies on the guide rail, and guide rail, current sensor, collector, computer expert cross lead and connect.Make its motion with the wire rod on the rapid sliding guides of hand during experiment, will on the reometer interface of computer screen, observe induction current and produce.
Described guide rail is certain thickness sheet metal.
Described magnet is strong magnet.
The utilization of the utility model device be simple and easy to material make, the utlity model has simple in structure, economy, effect obviously and stable, be suitable as advantages such as using of student experiment in group.
